Extreme weather worries across U.S. on Christmas Day

Updated 12:05 a.m. ET

Both coasts of the country are dealing with unusual weather this week during an especially challenging time. An estimated 93 million Americans are expected to drive or fly more than 50 miles from home for the holidays.

In the Sierra Mountains, they're dealing with three feet of snow in some spots.

From the possibility of tornados to heavy snowfall, there is great potential for a travel nightmare this holiday season. The fast-moving storm system is expected to have a significant impact on airport travel as it moves east.

Meteorologist Jeff Beradelli of CBS Miami station WFOR-TV said the southern storm system is looking like a classic severe weather setup, with warm, moist air from the Gulf of Mexico colliding with the jet stream to create unstable conditions. We may see howling thunderstorms and numerous, possibly strong tornados on Christmas Day.

The storms could bring strong tornadoes or winds of more than 75 mph, heavy rain, quarter-sized hail and dangerous lightning in Louisiana and Mississippi, the National Weather Service said. The greatest risk is in areas north of Interstates 10 and 12, with the worst storms likely along and southeast of a line from Winnsboro, La., to Jackson and DeKalb, Miss., according to the weather service's Jackson office.

Five holiday tips for the travel industry

On the northern side of the system, there's a possibility of a very wide swath of heavy snowfall.

That will be good news on Christmas Day for folks expecting a white Christmas, but this is going to turn into a travel nightmare as the system makes its way up through the Ohio Valley, into the Great Lakes and interior portions of the Northeast. Some places will see one to two feet of snow, especially upstate New York and interior Pennsylvania.

Much of Oklahoma and Arkansas were under a winter storm warning, with freezing rain, sleet and snow expected on Christmas. A blizzard watch is out for western Kentucky. No matter what form it takes, travel Tuesday could be dangerous, meteorologists said.

"We understand that most people will be focusing on the holiday," said Mississippi Gov. Phil Bryant. "Please plan now for how you will receive a severe weather warning, and know where you will go when it is issued. It only takes a few minutes, and it will help everyone have a safe Christmas."

In Alabama, the director of the Emergency Management Agency, Art Faulkner, said he was briefing both local officials and Gov. Robert Bentley on plans for dealing with a possible outbreak.

Forecasters said storms would begin near the Gulf Coast and spread north through the day, bringing with them the chances of storms, particularly in central and southwest Alabama. No day is good for severe weather, but Faulkner said Christmas adds extra challenges because people are visiting unfamiliar areas. Also, people are more tuned in to holiday festivities than their weather radio on a day when thoughts typically turn more toward the possibility of snow than twisters, he said.

In California, after a brief reprieve across the northern half of the state on Monday, wet weather was expected to make another appearance on Christmas. Flooding and snarled holiday traffic were also expected in Southern California.

Ten storm systems in the last 50 years have spawned at least one Christmastime tornado with winds of 113 mph or more (F-2) in the South, Chris Vaccaro, a National Weather Service spokesman in Washington, said in an email. The most lethal were the storms of Dec. 24-26, 1982, when 29 tornadoes in Oklahoma, Missouri, Arkansas, Tennessee and Mississippi killed three people and injured 32; and those of Dec. 24-25, 1964, when two people were killed and about 30 people injured by 14 tornadoes in seven states.

A National Weather Service statement from Jackson, Miss., said the main questions are how far north and west the threat will spread — and whether the storms will be more scattered, resulting in a greater tornado risk, or more in the form of a squall line, resulting in a higher risk of damaging straight-line winds along with embedded tornadoes.

Newtown Christmas: 'We Know They'll Feel Loved'

As residents prepared to observe Christmas less than two weeks after a gunman killed 20 children and six educators at an elementary school, people sharing in the town's mourning brought offerings of cards, handmade snowflakes and sympathy.

Tiny empty Christmas stockings with the victims' names on them hung from trees in the neighborhood where the children were shot. On Christmas Eve, residents said they would light luminaries outside their homes in memory of the victims.

"We know that they'll feel loved. They'll feel that somebody actually cares," said Treyvon Smalls, a 15-year-old from a few towns away who arrived at town hall with hundreds of cards and paper snowflakes collected from around the state.

At the Trinity Episcopal Church, less than 2 miles from the school, an overflow crowd of several hundred people attended Christmas Eve services. They were greeted by the sounds of a children's choir echoing throughout a sanctuary hall that had its walls decorated with green wreaths adorned with red bows.

The church program said flowers were donated in honor of Sandy Hook shooting victims, identified by name or as the "school angels" and "Sandy Hook families."

Gun Violence Victims, Survivors Share Thoughts After Newtown Massacre Watch Video

The service, which generally took on a celebratory tone, made only a few vague references to the shooting. Pastor Kathie Adams-Shepherd led the congregation in praying "that the joy and consolation of the wonderful counselor might enliven all who are touched by illness, danger, or grief, especially all those families affected by the shootings in Sandy Hook."

Police say the gunman, Adam Lanza, killed his mother in her bed before his Dec. 14 rampage and committed suicide as he heard officers arriving. Authorities have yet to give a theory about his motive.

While the grief is still fresh, some residents are urging political activism in the wake of the tragedy. A grassroots group called Newtown United has been meeting at the library to talk about issues ranging from gun control, to increasing mental health services to the types of memorials that could be erected for the victims. Some clergy members have said they also intend to push for change.

"We seek not to be the town of tragedy," said Rabbi Shaul Praver of Congregation Adath Israel. "But, we seek to be the town where all the great changes started."

Since the shooting, messages similar to the ones delivered Monday have arrived from around the world. People have donated toys, books, money and more. A United Way fund, one of many, has collected $3 million. People have given nearly $500,000 to a memorial scholarship fund at the University of Connecticut. On Christmas Day, police from other towns have agreed to work so Newtown officers can have the time off.

At Washington's National Cathedral, the 20 children who were killed also were remembered. Angels made of paper doilies were used to adorn the altar in the children's chapel. They'll be displayed there through Jan. 6.

In the center of Newtown's Sandy Hook section Monday, a steady stream of residents and out-of-towners snapped pictures, lit candles and dropped off children's gifts at an expansive memorial filled with stuffed animals, poems, flowers, posters and cards.

"All the families who lost those little kids, Christmas will never be the same," said Philippe Poncet, a Newtown resident originally from France. "Everybody across the world is trying to share the tragedy with our community here."

THIS was the year we held our breath in almost unbearable anticipation while we waited to see whether physicists at the Large Hadron Collider would finally get a clear view of the Higgs boson, so tantalisingly hinted at last December. Going a bit blue, we held on through March when one of the LHC's detectors seemed to lose sight of the thing, before exhaling in a puff of almost-resolution in July, when researchers announced that the data added up to a fairly confident pretty-much-actual-discovery of the particle.

Early indications were that it might be a weird and wonderful variety of the Higgs, prompting a collective gasp of excitement. That was followed by a synchronised sigh of mild disappointment when later data implied that it was probably the most boring possible version after all, and not a strange entity pointing the way to new dimensions and the true nature of dark matter. Prepare yourself for another puff or two as the big story moves on next year.

This respirational rollercoaster might be running a bit too slowly to supply enough oxygen to the brain of a New Scientist reader, so we have taken care to provide more frequent oohs and aahs using less momentous revelations. See how many of the following unfundamental discoveries you can distinguish from the truth-free mimics that crowd parasitically around them.

1. Which of these anatomical incongruities of the animal kingdom did we describe on 14 July?

• a) A fish, found in a canal in Vietnam, that wears its genitals under its mouth
• b) A frog, found in a puddle in Peru, that has no spleen
• c) A lizard, found in a cave in Indonesia, that has four left feet
• d) A cat, found in a tree in northern England, that has eight extra teeth

2. "A sprout by any other name would taste as foul." So wrote William Shakespeare in his diary on 25 December 1598, setting off the centuries of slightly unjust ridicule experienced by this routinely over-cooked vegetable. But which forbiddingly named veg did we report on 7 July as having more health-giving power than the sprout, its active ingredient being trialled as a treatment for prostate cancer?

• a) Poison celery
• b) Murder beans
• c) Inconvenience potatoes
• d) Death carrots

3. Scientists often like to say they are opening a new window on things. Usually that is a metaphor, but on 10 November we reported on a more literal innovation in the fenestral realm. It was:

• a) A perspex peephole set in the nest of the fearsome Japanese giant hornet, to reveal its domestic habits
• b) A glass porthole implanted in the abdomen of a mouse, to reveal the process of tumour metastasis
• c) A crystal portal in the inner vessel of an experimental thorium reactor, to reveal its nuclear fires to the naked eye
• d) A small window high on the wall of a basement office in the Princeton physics department, to reveal a small patch of sky to postgraduate students who have not been outside for seven years

4. On 10 March we described a new material for violin strings, said to produce a brilliant and complex sound richer than that of catgut. What makes up these super strings?

• a) Mousegut
• b) Spider silk
• c) Braided carbon nanotubes
• d) An alloy of yttrium and ytterbium

5. While the peril of climate change looms inexorably larger, in this festive-for-some season we might take a minute to look on the bright side. On 17 March we reported on one benefit of global warming, which might make life better for some people for a while. It was:

• a) Receding Arctic sea ice will make it easier to lay undersea cables to boost internet speeds
• b) Increasing temperatures mean that Greenlanders can soon start making their own wine
• c) Rising sea levels could allow a string of new beach resorts to open in the impoverished country of Chad
• d) More acidic seawater will add a pleasant tang to the salt water taffy sweets made in Atlantic City

6. In Alaska's Glacier Bay national park, the brown bear in the photo (above, right) is doing something never before witnessed among bearkind, as we revealed on 10 March. Is it:

• a) Making a phonecall?
• b) Gnawing at a piece of whalebone to dislodge a rotten tooth?
• c) Scratching itself with a barnacle-covered stone tool?
• d) Cracking oysters on its jaw?

7. Men have much in common with fruit flies, as we revealed on 24 March. When the sexual advances of a male fruit fly are rejected, he may respond by:

• a) Whining
• b) Hitting the booze
• c) Jumping off a tall building
• d) Hovering around the choosy female long after all hope is lost

8. While great Higgsian things were happening at the LHC, scientists puzzled over a newly urgent question: what should we call the boson? Peter Higgs wasn't the only physicist to predict its existence, and some have suggested that the particle's name should also include those other theorists or perhaps reflect some other aspect of the particle. Which of the following is a real suggestion that we reported on 24 March?

Egypt awaits referendum results; opposition cries fraud

CAIRO: Egypt on Monday was awaiting official results of a referendum on a new constitution reportedly backed by two-thirds of voters but which the opposition alleged was riddled with fraud.

"No official date has been fixed" for the final polling figures, a member of the electoral commission, Mohamed el-Tanobly, told AFP. State media had reported the count could be given on Monday.

The Muslim Brotherhood backing President Mohamed Morsi and media say an unofficial tally shows 64 percent of ballots backed the constitution.

But the National Salvation Front opposition coalition claims numerous instances of polling "fraud and violations" and is demanding the electoral commission investigate before issuing its official figures.

"The referendum is not the end of the road. It is only one battle," the Front also said in a statement. "We will continue the fight for the Egyptian people."

The challenge suggested no quick end to Egypt's political crisis, which erupted a month ago when Morsi allocated himself near-absolute powers to push through the charter written up by an Islamist-dominated panel.

Fierce protests, including violent clashes on December 5 that killed eight people and wounded hundreds, led to Morsi giving up those powers early this month.

Egypt remains a deeply polarised nation.

Morsi and his Muslim Brotherhood, testing newfound power after decades of being sidelined by ousted leader Hosni Mubarak, are spearheading changes to infuse the country with a more Islamist character favoured by the vast poorer part of the population. They say the new constitution will usher in stability.

Against them are ranged the largely urban, liberal, leftwing, Christian and secular supporters of the opposition who feel alienated by Morsi. They see ambiguities inserted in the charter as opening the way to future sharia-style strict Islamic law.

Germany echoed the call for an investigation into the alleged voting fraud, saying the new constitution can only be seen as valid "if the process of its adoption is beyond reproach."

The United States, which provides Egypt's powerful military with $1.3 billion in aid per year, has kept mostly quiet on the turmoil buffeting its key Middle East ally.

But the Republican chairwoman of the Foreign Affairs Committee in the US House of Representatives, Ileana Ros-Lehtinen, called the vote "a defeat for the Egyptian people" at the hands of "an Islamic dictatorship."

Iran, which is trying to claim the ongoing Arab Spring was inspired by its own 1979 Islamic revolution, welcomed the referendum by saying it promoted "progressive, Islamic and revolutionary goals" in Egypt.

The political storm in Egypt has deepened economic instability triggered by Mubarak's overthrow in 2011.

Morsi's government is grappling with climbing debt, plunging tourism revenue, a tottering currency and fleeing investors.

A $4.8 billion loan from the International Monetary Fund was put on hold this month, adding pressure on Egypt's central bank, whose foreign reserves have more than halved since Mubarak's ouster to less than $15 billion.

State television announced on the weekend that the central bank chief, Faruq El-Okda, was resigning -- before rapidly citing a cabinet source denying that.

"I'm more worried about the economic future of the country today than I was just a few weeks ago," Angus Blair, a veteran financial analyst and head of the Signet Institute think-tank in Cairo, told AFP.

"Voting yes in the constitutional referendum will not stop the economic malaise," he said.

Police crackdown amid outrage over gang rape

STORY HIGHLIGHTS

• Russian President Vladimir Putin is due visit India Monday


• New Delhi's government district is under a lockdown


• Protesters demonstrate after the gang rape of a woman on a bus


• Police say the woman was badly beaten and left for dead

New Delhi (CNN) -- Police locked down New Delhi's key government district ahead of Monday's visit by Russian President Vladimir Putin, after two days of pitched street battles following the gang rape of a woman on a bus.

Putin is scheduled to meet with Indian prime minister Manmohan Singh Monday afternoon and later with the Indian president.

Authorities erected security barriers throughout the city's Raisina Hills area -- home to the presidential mansion, the parliament building and federal ministerial blocks. Only those authorized to work in the district were allowed to pass.

Furious weekend demonstrations rocked Raisina Hills as public outrage surged after a 23-year-old woman was sexually assaulted and beaten to near death on a bus on December 16 by a group of six suspects, now under arrest, police say.

Singh again expressed solidarity with the rape victim in a televised address on Monday. He also reiterated an earlier appeal for calm and a pledge of safety for women and children.

On Sunday, incensed protesters defied a police ban on demonstrations, clashing repeatedly with police.

As officers sprayed water cannons, some dispersed, while others huddled tightly in a circle to brave high-pressure streams in the cold December weather.

"We want justice!" the protesters shouted in chorus.

In addition to banners and cardboard placards, many demonstrators carried Indian flags as they scuffled with police. Authorities also fired tear gas to try to break up crowds.

Police spokesman Rajan Bhagat said "hooligans who had joined the protesters" hurled stones, injuring 78 officers on Sunday. At least 65 protesters were also injured, he said.

Many police vans and a dozen public buses were damaged during the demonstrations, he said.

Buy Sunday night, the scene was cleared of all protesters.

Earlier in the day, Singh called for calm after clashes escalated.

"We will make all possible efforts to ensure security and safety to all women in this country," the Indian leader said. "I appeal to all concerned citizens to maintain peace and calm."

In his statement, Singh acknowledged that the anger is "genuine and justified."

Authorities haven't released the name of the rape victim, but protesters are calling her "Damini," which means "lightning" in Hindi.

"Damini" is also a 1993 Bollywood film whose lead female character fights for a housemaid, a victim of a sexual assault.

"We support you Damini. We'll keep fighting for you," a middle-aged woman at the historic India Gate said Sunday. "Damini wants justice," read a placard at the protest.

The rape victim's injuries were so severe she spent days in intensive care in a city hospital, battling for her life. Police said Saturday that she had recovered enough to give a statement to a magistrate from her hospital bed the night before.

But on Sunday, she underwent another surgery to wash out infection in her abdomin, her doctors said.

The protests were among many anti-rape demonstrations staged across the country over the past week.

A video journalist was killed by police gunfire Sunday during a violent protest in India's remote northeastern state of Manipur, authorities said.

The journalist, identified by the information and broadcasting ministry as Dhij Mani, was covering a protest against a separate molestation case in the provincial capital of Imphal.

Protests have rocked Manipur over the alleged molestation of a local actress by a suspected militant on December 18, during a public performance, authorities say.

Protesters torched a vehicle, forcing police to open fire, officer Manik Longjam said Sunday.

The journalist died in the gunfire, Longjam said.

Police say the molester is still at large.

Reported rape cases have increased more than tenfold over the past 40 years -- from 2,487 in 1971 to 24,206 in 2011, according to official figures.

New Delhi alone reported 572 rapes last year and more than 600 in 2012.

As fury about the assault gathered pace, some Indian lawmakers called for treating rape as a capital crime.

"We'll work collectively to see we make a law which is deterrent and preventive," said New Delhi's chief minister, Sheila Dikshit.

India's home minister Sushilkumar Shinde told reporters Saturday that the government would work toward increasing punishment in "rarest of the rare" rape cases.

But pressed on whether the administration would agree to demands for death by hanging in such instances, he said: "We'll have to see in what way it (the rape sentencing) can be enhanced."

Shinde said the government was pushing for a speedy trial for the attack.

Authorities are also taking a number of steps to improve security for women in New Delhi, particularly on public transport, he said.

"(The) government shares the widespread concern and support that has been expressed throughout society for the girl who has so suffered. Government also respects the right of legitimate protest," Shinde said.

"At the same time, there is need to exercise calm at this juncture and for everyone to work together to improve the safety and security environment."

American killed by Afghan policewoman

KABUL, Afghanistan An Afghan police official says an Afghan policewoman has killed an American adviser at the Kabul police headquarters.

Kabul's Deputy Police Chief, Mohammad Daoud Amin, says an investigation is under way to determine whether the killing Monday was intentional or accidental.

Charles Stadtlander, a spokesman for the International Security Assistance Force, the U.S.-led military coalition, tells CBS News the victim was a civilian and the assailant is in custody.

More than 50 international troops have been killed by Afghan soldiers or police this year, and a number of other assaults -- known as "insider attacks" -- are still being probed.

This would apparently be the first such attack involving a female assailant.

NATO forces, due to mostly withdraw from the country by 2014, have sped up efforts to train and advise Afghan military and police units before the pullout.

The surge in insider attacks is throwing doubt on the capability of the Afghan security forces to take over from international troops and has further undermined public support in NATO countries for the 11-year war.

More than 50 Afghan members of the government's security forces also have died this year in attacks by their own colleagues.

Taliban militants claim such attacks reflect a growing popular opposition to both foreign military presence and the Kabul government.

Get 'em While You Can? Gun Sales Soar

The National Rifle Association may still get its way and defeat the lawmakers calling for a ban on the sale of assault ridles, but some gun store owners say it seems their customers aren't taking any chances.

"We have never seen anything like this," said Larry Hyatt, who owns a gun shop in Charlotte, N.C. "We have the Christmas business, the hunting season business, and now we have the political business.

"We have seen a lot of things, but we have never seen anything like this, this is probably four times bigger than the last time we saw a big rush," he said.

Some of the customers in his store said it is the talk of stricter gun control in the wake of the shooting at the Sandy Hook Elementary School in Newtown, Conn., that is driving the rush.

"The way they are trying to approach it, they are just making people who have never thought about buying a gun, now they want to come in here and buy a gun," one customer said.

At NOVA Firearms in Falls Church, Va., there have been "skyrocketing" sales following the Newtown shooting, chief firearms instructor Chuck Nesby said.

"They've been off the charts. Absolutely skyrocketing," Nesby said. "If I could give an award to President Obama and Senator Feinstein would be sales persons of the year."

He was referring to Sen. Dianne Feinstein, D-Calif., who said she will introduce an assault weapons ban in January.

Sales are up 400 percent, he said.

"We're completely out of the so-called assault weapons, semi automatic firearms that are rifles," Nesby said. "Forty percent of those sales went to women and senior citizens. We can't get them now. Everybody, nationwide is out of them the sales have just been off the charts nationwide."

National Rifle Association News Conference Interrupted by Protesters Watch Video

The horrific shooting, when 20-year-old Adam Lanza broke in to the elementary school and killed 20 children and six adults with a semi-automatic rifle, has even some former NRA supporters saying it's time to change the rules on assault weapons.

Those guns were banned from 1994 until 2004, when the ban expired and was not renewed.

Now it's not just lawmakers who have traditionally advocated stricter gun control talking about the need to act.

Republican Sen. Kay Bailey Hutchison of Texas suggested today on CBS' "Face the Nation" that new regulation should be considered.

"We ought to be looking at where the real danger is, like those large clips, I think that does need to be looked at," Hutchison said. "It's the semi-automatics and those large magazines that can be fired off very quickly. You do have to pull the trigger each time, but it's very quick."

Virginia Sen. Mark Warner, a Democrat but a long-time opponent of gun control who like Hutchison has received an A rating from the NRA, has also come out in support of strengthening gun laws.

NRA chief Wayne LaPierre said Friday that more gun control is not the way to stop such shooting from happening again: the answer is more guns, in the form of armed guards in every school.

After being criticized for two days for the proposal, LaPierre today stuck by his guns.

"If it's crazy to call for putting police and armed security in our schools to protect our children, then call me crazy," he said on NBC's "Meet the Press."

"When that horrible monster tried to shoot his way into Sandy Hook school, that if a good guy with a gun had been there, he might have been able to stop [it]," LaPierre said.

LaPierre and the NRA said that the media, the entertainment culture and lack of proper mental health care are to blame, not the proliferation of guns in the United States.

Asa Hutchinson, the former congressman who will lead the effort by the NRA to place armed security guards in schools across the country, said today on "This Week" that gun control efforts would not be part of the "ultimate solution" to gun violence.

How does a traffic cop ticket a driverless car?

Rapid progress means self-driving cars are in the fast lane to consumer reality. Is the law up to speed too, asks legal expert Bryant Walker Smith

EVER since the 1930s, self-driving cars have been just 20 years away. Many of those earlier visions, however, depended on changes to physical infrastructure that never came about - like special roads embedded with magnets.

Fast forward to today, and many of the modern concepts for such vehicles are intended to work with existing technologies. These supercomputers-on-wheels use a variety of onboard sensors - and, in some cases, stored maps or communications from other vehicles - to assist or even replace human drivers under specific conditions. And they have the potential to adapt to changes in existing infrastructure rather than requiring it to alter for them.

Infrastructure, however, is more than just roads, pavements, signs and signals. In a broad sense, it also includes the laws that govern motor vehicles: driver licensing requirements, rules of the road and principles of product liability, to name but a few. One major question remains though. Will tomorrow's cars and trucks have to adapt to today's legal infrastructure, or will that infrastructure adapt to them?

Consider the most basic question: are self-driving vehicles legal today? For the US, the short answer is that they probably can be (the long answer runs to nearly 100 pages). Granted, such vehicles must have drivers, and drivers must be able to control their vehicles - these are international requirements that date back to 1926, when horses and cattle were far more likely to be "driverless" than cars. Regardless, these rules, and many others that assume a human presence, do not necessarily prohibit vehicles from steering, braking and accelerating by themselves. Indeed, three US states - Nevada, Florida and most recently California - have passed laws to make that conclusion explicit, at least to a point.

Still unclear, even with these early adopters, is the precise responsibility of the human user, assuming one exists. Must the "driver" remain vigilant, their hands on the wheel and their eyes on the road? If not, what are they allowed to do inside, or outside, the vehicle? Under Nevada law, the person who tells a self-driving vehicle to drive becomes its driver. Unlike the driver of an ordinary vehicle, that person may send text messages. However, they may not "drive" drunk - even if sitting in a bar while the car is self-parking. Broadening the practical and economic appeal of self-driving vehicles may require releasing their human users from many of the current legal duties of driving.

For now, however, the appropriate role of a self-driving vehicle's human operator is not merely a legal question; it is also a technical one. At least at normal speeds, early generations of such vehicles are likely to be joint human-computer systems; the computer may be able to direct the vehicle on certain kinds of roads in certain kinds of traffic and weather, but its human partner may need to be ready to take over in some situations, such as unexpected road works.

A great deal of research will be done on how these transitions should be managed. Consider, for example, how much time you would need to stop reading this article, look up at the road, figure out where you are and resume steering and braking. And consider how far your car would travel in that time. (Note: do not attempt this while driving your own car.)

Technical questions like this mean it will be a while before your children are delivered to school by taxis automatically dispatched and driven by computers, or your latest online purchases arrive in a driver-less delivery truck. That also means we have time to figure out some of the truly futuristic legal questions: How do you ticket a robot? Who should pay? And can it play (or drive) by different rules of the road?

Data protection is a more pressing issue. Many cars and trucks available today already collect driving data through onboard sensors, computers and cellular devices. But imagine taking a dozen smartphones, turning on all of their sensors and cameras, linking them to your social media accounts, and affixing them to the inside and outside of your vehicle. That is an understatement of a self-driving vehicle's potential data collection. Because consumer versions of such vehicles do not yet exist, we don't know what data will actually be collected or how it will be transmitted and used. However, legal issues related to disclosure, consent and ownership will mix with important policy questions about the costs and benefits of data sharing. Indeed, some research vehicles in Germany already have privacy notices printed on their sides to warn other road users.

Finally, what happens when things go wrong - or at least not as right as they might? Given that the vast majority of crashes are caused at least in part by human error, self-driving vehicles have huge potential to save lives. But they will not be perfect; after all, humans will remain in the design loop even after they are out of the driving loop. To what standard, then, should these vehicles be held? Must they perform as well as a perfect human driver for any conceivable manoeuvre? Or must they perform merely as well as an average human in a statistical sense? In any case, how should that performance be measured?

These questions will be considered explicitly or implicitly by the regulators who create new standards, the judges and juries that decide who should pay for injuries, and how much, and the consumers who decide what kind of car to buy. The uncertainty that surrounds the answers will affect the speed and price at which these new technologies are introduced.

Why do these questions matter so much? Because ultimately their most meaningful answers will, one hopes, be expressed in terms of lives saved.

Bryant Walker Smith is a fellow at the Center for Internet and Society at Stanford Law School and the Center for Automotive Research at Stanford University, California. His analysis of the legality of self-driving vehicles in the US came out in November (bit.ly/SVCe32)

More S'poreans fall prey to phone scams

SINGAPORE: More Singaporeans fell prey to lucky draw phone scams in the first eight months of the year.

Police said there were 234 reported cases in the period, of which 134 victims were cheated of their money.

Between January and August last year, there were 201 reported cases of lucky draw phone scams and 123 victims who were cheated.

The amount of money cheated from victims went up by 21 per cent to S$4.6 million, compared to S$3.8 million in the same period last year.

Police said victims include professionals, youths and senior citizens.

Tricksters would typically call their victims and inform them that they have won a prize in a lucky draw overseas.

In order to redeem the prize, which could be a luxury car or air tickets, the victim will have to pay a processing fee or tax upfront.

After receiving the first payment via bank transfers, the tricksters would ask for subsequent payments.

The victim usually realises he or she has been cheated when the culprit becomes uncontactable.

Police advised the public to call 999 immediately if they receive a lucky draw phone scam call.

The public should not make any advance payment to claim any prize.

Little common ground in debate on guns

STORY HIGHLIGHTS

• The NRA wants to staff every school in America with "qualified armed security"


• Obama, Democrats and others see tougher gun control as the way to limit future massacres


• While both sides want to keep children safe, it seems they are living in two different worlds

Washington (CNN) -- For National Rifle Association Vice President Wayne LaPierre and many other pro-gun Americans, the task is clear: The best way to protect children from becoming victims of a slaughter like the one seen last week in Newtown, Connecticut, is to make sure every school in America has "qualified armed security."

For President Barack Obama, many Democratic leaders and a slight majority of the American public, the solution starts with tougher legislation on assault weapons, universal background checks and limits on high-capacity magazines, the first steps needed to begin to make it harder to get at the kinds of firearms that kill thousands of Americans each year.

Both sides are so vested in intractable arguments that there is little room for political common ground. While both sides share a desire to keep children safe, it's like they are living in two different worlds.

On one side, the gun rights advocates argue that a well-armed populace can best defend the innocent. They say that if the teachers at Sandy Hook Elementary School were armed -- or if there were armed security at the front door -- fewer lives would have been lost.

On the other side, the gun control advocates are fighting to protect lives by limiting access to guns. They say that if the weapons used in the Newtown massacre weren't so readily available -- there are at least 310 million non-military firearms in the U.S. today -- then the 27 people who were murdered might still be alive.

"It's hard for people to come to the table to at least talk about it," said Alan Lizotte, dean and professor at the State University of New York at Albany's School of Criminal Justice.

Why would someone own a military-style rifle?

It took the NRA -- the nation's most politically powerful gun lobby that boasts 4.3 million members -- one week and a bizarre press conference-turned-one-way-announcement to do just that.

Where some may have hoped for concessions on the NRA's staunch pro-gun, guns-don't-kill-people-people-kill-people stance, the NRA stayed the course, and even doubled down. They offered no willingness to consider any of the proposals offered this week to amend gun laws including limiting access to assault weapons, requiring universal background checks, limiting sales at gun shows and increasing the use of trigger locks.

Instead, the group pointed to media sensationalism, violent video games, gun-free zones in schools, the failure to enforce gun laws already on the books, issues with the nation's mental health system and other societal problems as feeding the spate of gun violence.

NRA clear on gun debate stance: arm schools

They then announced a new national program to train and arm thousands of armed security to be stationed at each of the nation's nearly 100,000 public and 33,000 private schools. They point to the fact that Sandy Hook Elementary School -- and most other schools in America -- are considered gun-free zones as a reason why it was easily attacked.

Policies banning guns at schools create a place that "insane killers" consider "the safest place to inflict maximum mayhem with minimum risk," LaPierre, said Friday. LaPierre said U.S. society has left children "utterly defenseless."

"The only thing that stops a bad guy with a gun is a good guy with a gun," he said.

The organization also indicated that it would push back against a growing legislative movement to introduce or, in some cases, reintroduce gun control legislation.

"We can't lose precious time debating legislation that won't work," LaPierre said.

The NRA's hard line came in stark contrast to President Obama's own plan after the Newtown shooting.

Obama appealed to the pro-gun lobby who he said "has members who are mothers and fathers" likely impacted by the shooting. But then he also invited them to "do some self-reflection."

Authorities must work to make "access to mental health care at least as easy as access to a gun," and the country needs to tackle a "culture that all too often glorifies guns and violence," he said.

Obama tapped Vice President Joe Biden to lead an administration effort to develop recommendations in January for preventing another tragedy like the Newtown school shooting.

"This is not some Washington commission. This is not something where folks are going to be studying the issue for six months and publishing a report that gets read and then pushed aside," Obama said Wednesday. "This is a team that has a very specific task to pull together real reforms right now."

Across the rest of the nation, attitudes about guns appear to be changing.

A CNN/ORC International poll released Wednesday indicated that a slight majority now favor major restrictions on owning guns or an outright ban on gun ownership by ordinary citizens and more than 6 in 10 favor a ban on semi-automatic assault rifles.

Forty-three percent said the shootings in Connecticut make them more likely to support gun control laws, a 15-point increase from January 2011 following the Arizona gun rampage that wounded U.S. Rep. Gabrielle Giffords. Half of those questioned said the school shootings have not changed their opinions on gun control, down 19 points from January 2011.

But there's an ocean of difference between the two sides, a gulf broadened by heated rhetoric and an almost singular focus on being "right."

NRA comments draw swift opposition in reactions

While gun control advocate New York Mayor Michael Bloomberg called the NRA's stance "a shameful evasion of the crisis facing our country," gun rights proponent and economist John Lott applauded the group for "coming out strongly questioning these gun free zones."

Connecticut senator-elect Chris Murphy tweeted his disgust after seeing the NRA's statement: "Walking out of another funeral and was handed the NRA transcript. The most revolting, tone deaf statement I've ever seen," he said on Twitter.

Former Republican National Committee Chairman and NRA supporter Michael Steele called the NRA's remarks "very haunting and very disturbing."

New Jersey Gov. Chris Christie, considered by some as a potential 2016 Republican presidential candidate, also disagreed with the NRA's position. "You don't want to make this an armed camp for kids," he said at an event in Newark Friday morning. "I don't think that's a positive example for children. We should be able to figure out other ways to enhance safety."

The differences both in perspective and approach couldn't be more divergent, folks on both sides of the issue point out.

"I think that people are hard wired differently. If you look at the world as a beautiful place and I'm in the arts, I'm a composer, I write music, I write poetry, if you believe the world's a beautiful place, your viewpoint is different than if you feel 'I have to have my guns to protect myself,' " said Hollis Thoms, 64, from Annapolis, Maryland, as he protested outside of the Willard InterContinental Hotel just after the NRA's press conference.

That's exactly the type of rhetoric that baffles Paul Martin, who commented on CNN.com.

"I am a gun owner. I would be in favor of a ban on assault type weapons, and limiting magazines to a max of 10 rounds. It's the crazies that say 'ban all weapons' that make me nervous about giving any ground at all," Martin wrote.

"Approach it reasonably, with assurances that you won't go bonkers and demand a total ban, and you might make progress. Approach it just from anger and you will be fought all the way."
