Robot inquisition keeps witnesses on the right track

MEMORY is a strange thing. Just using the verb "smash" in a question about a car crash instead of "bump" or "hit" causes witnesses to remember higher speeds and more serious damage. Known as the misinformation effect, it is a serious problem for police trying to gather accurate accounts of a potential crime. There's a way around it, however: get a robot to ask the questions.

Cindy Bethel at Mississippi State University in Starkville and her team showed 100 "witnesses" a slide show in which a man steals money and a calculator from a drawer, under the pretext of fixing a chair. The witnesses were then split into four groups and asked about what they had seen, either by a person or by a small NAO robot, controlled in a Wizard of Oz set-up by an unseen human.

Two groups - one with a human and one a robot interviewer - were asked identical questions that introduced false information about the crime, mentioning objects that were not in the scene, then asking about them later. When posed by humans, the questions caused the witnesses' recall accuracy to drop by 40 per cent - compared with those that did not receive misinformation - as they remembered objects that were never there. But misinformation presented by the NAO robot didn't have an effect.

"It was a very big surprise," says Bethel. "They just were not affected by what the robot was saying. The scripts were identical. We even told the human interviewers to be as robotic as possible." The results will be presented at the Human-Robot Interaction conference in Tokyo next month.

Bilge Mutlu, director of the Human-Computer Interaction Laboratory at the University of Wisconsin-Madison, suggests that robots may avoid triggering the misinformation effect simply because we are not familiar with them and so do not pick up on behavioural cues, which we do with people. "We have good, strong mental models of humans, but we don't have good models of robots," he says.

The misinformation effect doesn't only effect adults; children are particularly susceptible, explains the psychologist on the project, Deborah Eakin. Bethel's ultimate goal is to use robots to help gather testimony from children, who tend to pick up on cues contained in questions. "It's a huge problem," Bethel says.

At the Starkville Police Department, a 10-minute drive from the university, officers want to use such a robotic interviewer to gather more reliable evidence from witnesses. The police work hard to avoid triggering the misinformation effect, says officer Mark Ballard, but even an investigator with the best intentions can let biases slip into the questions they ask a witness.

Children must usually be taken to a certified forensic child psychologist to be interviewed, something which can be difficult if the interviewer works in another jurisdiction. "You might eliminate that if you've got a robot that's certified for forensics investigations, and it's tough to argue that the robot brings any memories or theories with it from its background," says Ballard.

The study is "very interesting, very intriguing", says Selma Sabanovic, a roboticist at Indiana University. She is interested to see what happens as Bethel repeats the experiment with different robot shapes and sizes. She also poses a slightly darker question: "How would you design a robot to elicit the kind of information you want?"

It's all about how you say it

When providing new information, rather than helping people recall events (see main story), a robot's rhetoric and body language can make a big difference to how well it gets its message across.

Bilge Mutlu of the University of Wisconsin-Madison had two robots compete to guide humans through a virtual city. He found that the robot which used rhetorical language drew more people to follow it. For example, the robot saying "this zoo will teach you about different parts of the world" did less well than one saying "visiting this zoo feels like travelling the world, without buying a plane ticket". The work will be presented at the Human-Robot Interaction conference in Tokyo next month.

Part of Circle Line to close on 17 March, shuttle service to be provided

SINGAPORE: The stretch between the Mountbatten and Dakota stations on the Circle Line (CCL) will not be operational on Sunday 17 March, from 5.30am to 10am.

This is to allow engineers to continue doing cable replacement works.

The Land Transport Authority (LTA) and SMRT said train services between Mountbatten and Paya Lebar stations will run as a shuttle service during that period.

During the shuttle service, normal service trains will stop at either Mountbatten or Paya Lebar station.

Commuters continuing their journey on the CCL will need to alight at one of these two stations and board the shuttle train at the opposite platform.

Commuters can then get off at the other station and continue their journey on the normal service train.

LTA and SMRT said the cable replacement at all 30 CCL stations is expected to be completed by December 2013, about half a year earlier than the 18-month timeline previously announced.

Works are currently ongoing for the first phase covering CCL stations from Dhoby Ghaut to Esplanade.

This will be followed by stations from Mountbatten to Tai Seng, Promenade to Stadium, Bartley to Marymount, Caldecott to one-north and Kent Ridge to HarbourFront.

The last phase will involve cables along Marina Bay and Bayfront.

STORY HIGHLIGHTS

• NEW: With snow coming, authorities continue to hunt for the suspect near Big Bear Lake


• Police believe former cop Christopher Jordan Dorner shot three officers, killing one


• This was days after he allegedly killed two people, one a retired LAPD officer's daughter


• In an 11-page manifesto, Dorner promises "war" on police and their families

Los Angeles (CNN) -- A former Los Angeles cop with military training vowed war against other men in blue Thursday, leaving one officer dead days after he allegedly killed two other people to begin a wave of retribution for being fired, police said.

The focus of the intensive, expansive manhunt is Christopher Jordan Dorner, a 270-pound former Navy lieutenant who has professed his venom against LAPD officers he claimed ruined his life by forcing him out of his dream job.

Dorner blames one retired officer for bungling his appeal to get his job back in an 11-page manifesto, in which he also complained of mistreatment by the LAPD. In that letter -- provided to CNN by an LAPD source -- he vowed to violently target police officers and their families, whoever and wherever they are.

"I will bring unconventional and asymmetrical warfare to those in LAPD uniform whether on or off duty," Dorner wrote.

"I never had the opportunity to have a family of my own, I'm terminating yours."

Authorities believe he followed through on his threats early Thursday by shooting a Riverside, California, police officer and two others. A day earlier, Irvine police named Dorner a suspect in the double slayings Sunday of a woman -- identified by Los Angeles police as the daughter of a retired LAPD officer -- and her fiance.

"My opinion of the suspect is unprintable," said Riverside police Chief Sergio Diaz, hours after one of his officers was killed. "The manifesto, I think, speaks for itself (as) evidence of a depraved and abandoned mind and heart."

The violence, as well as Dorner's background as a police officer and military trained marksman, left police on edge around Southern California.

In Torrance, LAPD officers guarding one of Dorner's alleged targets mistakenly opened fire on a blue pickup truck that resembled one Dorner was thought to be driving, said Los Angeles police Chief Charlie Beck.

The gunfire left two people wounded, Beck said. Torrance police also fired on another blue pickup, but no one was injured in that incident, according to a senior law enforcement source.

In downtown Los Angeles, police wearing body armor patrolled outside their own iconic headquarters.

Police have good reason to be fearful, the chief said.

"Of course, he knows what he's doing. We trained him," Beck said. "He was also a member of the armed forces. It is extremely worrisome and scary, especially to the officers involved."

The manhunt for Dorner spanned hundreds of miles and numerous counties. By Thursday afternoon, it was largely centered around Big Bear Lake -- about 100 miles east of Los Angeles -- where authorities found the truck the suspect allegedly used in the Riverside shooting.

KTLA: Manhunt for former cop after officers shot

Police confirmed that the vehicle, which was burnt out when it was found, belonged to Dorner by its vehicle identification number, San Bernardino County Sheriff John McMahon said.

This discovery spurred more officers to converge on the area to conduct beefed up patrols, staff checkpoints and go to every residence in the mountain community. McMahon acknowledged the fire may have been set as a diversionary tactic, though law enforcement isn't taking any chances. Early Thursday evening, he said that aerial and K9 searches on the ground will "continue as long as we can" -- though snow is coming -- and urged locals to be on alert.

"He could be anywhere at this point, and that's why we're searching door to door," the sheriff said.

1 cop dies in 'cowardly ambush'

It all started Sunday when Dorner allegedly killed two people in Irvine, according to police.

Police identified the victims as Monica Quan and her fiance Keith Lawrence.

Quan, 27, was the daughter of retired Los Angeles police Officer Randal Quan, LAPD Officer Tenesha Dobine told CNN. In his manifesto, Dorner said Quan handled his appeal.

On Tuesday, Dorner checked into the Navy Gateway Inns and Suites on San Diego's large naval base, Cmdr. Brad Fagan said.

Dorner likely had access to the hotel because he'd been honorably discharged from the Navy Reserve, said the Navy spokesman. Having retired February 1 as a lieutenant, Dorner worked with mobile inshore undersea warfare units and provided security on oil platforms in Iraq, according to Pentagon records. He was rated as a rifle marksman and pistol expert.

"He did not physically check out" Wednesday as expected, Fagan told reporters.

Police in San Diego say a man who could have been Dorner tried to hijack a boat there on Wednesday. Someone later found a wallet containing Dorner's identification and an LAPD detective's badge near the San Diego airport, according to police. It was unclear whether the badge was legitimate.

Timeline in manhunt for former L.A. cop

By about 1 a.m. Thursday, the scene had shifted about 100 miles north to Corona, California.

There, a pair of LAPD officers on a protection detail were flagged down by a citizen who reported seeing the suspect's vehicle, LAPD Deputy Chief Jose Perez said.

The officers chased the vehicle and caught up to it on an Interstate 15 off-ramp.

"The officers were fired upon with a shoulder weapon," Perez said, with one of them suffering a "graze wound" to his head. The police returned fire, while the suspect set off once again.

About 20 minutes later, two police officers were in their car at a stop light in Riverside when Dorner allegedly pulled up beside them.

That driver unleashed "multiple rounds" from a rifle at the officers, riddling the cop car with bullets and leaving a 34-year-old officer, who had been on the Riverside force for 11 years, dead, according to Diaz. The other officer, 27, was "seriously wounded but we expect a full recovery," the Riverside police chief said.

KCBS: Riverside officer fatally shot

It was "a cowardly ambush," said Diaz, claiming Dorner has "no connection" to his city.

A good Samaritan picked up one of their police radios and called dispatchers to send help, Riverside police said.

Suspect calls attacks 'a necessary evil'

In addition to posting his manifesto online, Dorner reached out directly to CNN, mailing a parcel to AC360 anchor Anderson Cooper's office at CNN in New York.

The package arrived on February 1 and was opened by Cooper's assistant. Inside was a hand-labeled DVD, accompanied by a yellow Post-it note reading, in part, "I never lied" -- apparently in reference to his 2008 dismissal from the LAPD.

The package also contained a coin wrapped in duct tape. The tape bears the hand-written inscription: "Thanks, but no thanks, Will Bratton." It also had letters that may be read as "IMOA", which could be a commonly used Internet abbreviation for "Imagine a More Open America," or possibly "1 MOA," which means one minute of angle, perhaps implying Dorner was notably accurate with a firearm.

The coin is a souvenir medallion from former LAPD Chief William Bratton, of a type often given out as keepsakes. This one, though, was shot through with bullet holes: three bullet holes to the center and another shot nicked off the top.

The editorial staff of AC360 and CNN management were made aware of the package Thursday. Upon learning of its existence, they alerted Bratton and law enforcement.

Bratton headed the LAPD at the time Dorner was dismissed.

The dispute centers on a 2007 incident in San Pedro involving a man's arrest at a DoubleTree hotel. Two weeks later, Dorner accused his training officer of kicking the man after he'd given up.

The investigators' report said "the delay in reporting the alleged misconduct coupled with the witness' statements irreparably destroy Dorner's credibility." The report cited contradictory accounts from the arrested man and his father and denials by the accused officer and three hotel employees that the arrested man had been kicked. Dorner claims he was wrongly ousted for blowing the whistle on what he insists was police abuse.

Suspect's grudge dates back to 2007 complaint

Dorner challenged his firing for years, losing at every turn. First, the police department's Board of Rights rejected his appeal. Then, in October 2011, a judge ruled against his appeal, according to court records.

Beck, the Los Angeles police chief, said Thursday that Dorner's case had been "thoroughly reviewed" and said the department would not apologize to Dorner or clear his name.

But as his manifesto shows, Dorner is showing no sign of relenting.

He complained he had been railroaded out of the department after reporting police brutality by another officer. Dorner also complained of a continuing culture of racism and brutality in the LAPD.

Attacks on other police officers and their families, he said, are "a necessary evil that I do not enjoy but must partake and complete for substantial change to occur within the LAPD and reclaim my name."

"Look your wives/husbands and surviving children directly in the face and tell them the truth as to why your children are dead," Dorner wrote.

Such a chilling warning prompted Los Angeles police to set up 40 protective details in an effort to safeguard people listed in Dorner's letter, Beck said.

The chief acknowledged that this effort was taxing the department, which has been placed under tactical alert, meaning all officers must stay on duty.

"It's extremely, extremely manpower intensive," Beck said. "But the safety of my employees, people that come on the job to protect the lives of strangers, is extremely important to me. And I will expend whatever resource is necessary."

LOS ANGELES Law enforcement officials are inspecting a package CNN's Anderson Cooper received from a former Los Angeles police officer who allegedly killed three in a shooting spree.

CNN spokeswoman Shimrit Sheetrit said Thursday that a parcel containing a note, a DVD and a bullet hole-riddled memento were sent by Christopher Dorner and addressed to Cooper's office.

LAPD Cmdr. Andrew Smith says LAPD robbery-homicide detectives will inspect the package for clues.

The package arrived Feb. 1, days before the first two killings Dorner is accused of.

It contained a note on it that read, in part, "I never lied."

Dorner was fired from the LAPD in 2008 for making false statements.

A coin typically given out as a souvenir by the police chief was also in the package, and riddled with bullet holes.

Cop Shooting Rampage: Manhunt on Mountain

The truck owned and driven by suspected cop killer Christopher Dorner during his alleged rampage through the Los Angeles area was found deserted and in flames on the side of Bear Mountain, Calif., this afternoon -- with tracks in the snow leading away from the vehicle.

The San Bernadino Sheriff's Department confirmed the truck was Dorner's, but said at a news conference this evening that the tracks around the truck did not lead to him.

Personnel from several departments and teams of dogs continued to search the area near Big Bear Lake, about 80 miles east of Los Angeles, including door-to-door searches of cabins located there, officials said.

Dorner, a former Los Angeles police officer and Navy reservist, remained on the loose.

"He could be anywhere, at this point, and that's why we're searching door to door," San Bernardino County Sheriff John McMahon said.

He added that the search would continue as long as it was possible. However, a snowstorm was forecast for the area.

Dorner was believed to have killed one police officer and injured two others early this morning in Riverside, Calif. He was also accused of killing two civilians on Sunday. And he allegedly released an angry "manifesto" airing grievances against police and warning of coming violence toward cops.

Heavily armed officers spent much of Thursday searching for signs of Dorner, investigating multiple false leads into his whereabouts and broadcasting his license plate and vehicle description across the California Highway System.

Around 12:45 p.m. PT, police responded to Bear Mountain, where two fires were reported, and set up a staging area in the parking lot of a ski resort. They did not immediately investigate the fires, but heavily armed SWAT team members eventually descended onto Bear Mountain from a helicopter manned with snipers to investigate and reached the truck.

Also today, CNN's Anderson Cooper said Dorner had sent him a package at his New York office that arrived on Feb. 1, though Cooper said he never knew about the package until today. It contained a DVD of court testimony, with a Post-It note signed by Dorner claiming, "I never lied! Here is my vindication."

It also contained a keepsake coin bearing the name of former Los Angeles Police Chief William J. Bratton that came wrapped in duct tape, Cooper said. The duct tape bore the note, "Thanks, but no thanks Will Bratton."

Bratton told Cooper on his program, "Anderson Cooper 360," that he believed he gave Dorner the coin as he was headed overseas for the Navy, Bratton's practice when officers got deployed abroad. Though a picture has surfaced of Bratton, in uniform, and Dorner, in fatigues, shaking hands, Bratton told Cooper he didn't recall Dorner or the meeting.

PHOTOS: Former LAPD Officer Suspected in Shootings

Police officers across Southern California were on the defensive today, scaling back their public exposure, no longer responding to "barking-dog calls" and donning tactical gear outdoors.

Police departments have stationed officers in tactical gear outside police departments, stopped answering low-level calls and pulled motorcycle patrols off the road in order to protect officers who might be targets of Dorner's alleged rampage.

"We've made certain modifications of our deployments, our deviations today, and I want to leave it at that, and also to our responses," said Chief Sergio Diaz of the police department in Riverside, Calif., where the officers were shot. "We are concentrating on calls for service that are of a high priority, threats to public safety, we're not going to go on barking dog calls today."

Sgt. Rudy Lopez of the Los Angeles Police Department said Dorner is "believed to be armed and extremely dangerous."

Early Thursday morning, before they believe he shot at any police officers, Dorner allegedly went to a yacht club near San Diego, where police say he attempted to steal a boat and flee to Mexico.

He aborted the attempted theft when the boat's propeller became entangled in a rope, law enforcement officials said. It was then that he is believed to have headed to Riverside, where he allegedly shot two police officers.

"He pointed a handgun at the victim [at the yacht club] and demanded the boat," said Lt. David Rohowits of the San Diego Police Department.

Police say the rifle marksman shot at four officers in two incidents overnight, hitting three of them: one in Corona, Calif., and the two in Riverside, Calif.

Tunisia pledges new govt after opposition leader's killing

TUNIS: Tunisia's premier has pledged to form a government of technocrats ahead of new elections, after the murder of opposition leader Chokri Belaid sparked deadly protests and attacks on the ruling party's offices.

Furious demonstrators built barricades in central Tunis on Wednesday and clashed with police, and four opposition groups including Belaid's Popular Front bloc said they were pulling out of the national assembly.

One policeman was killed after being hit on the chest by rocks in Tunis, the interior ministry said, while an ambulance carrying Belaid's body to the city centre was accompanied by crowds who pressed against the vehicle to protect it.

Islamist Prime Minister Hamadi Jebali said in a televised address after Belaid was shot dead outside his home in Tunis on Wednesday that he would form a new, non-political administration ahead of fresh elections.

"I have decided to form a government of competent nationals without political affiliation, which will have a mandate limited to managing the affairs of the country until elections are held in the shortest possible time," he said.

Jebali did not specify that he was dissolving the existing government, nor did he set a date for the reshuffle which must be confirmed by the national assembly.

President Moncef Marzouki denounced the killing of Belaid, an outspoken critic of his government, as an "odious assassination".

The ruling Islamist Ennahda party, which Belaid's family accused of being behind the killing, rejected any involvement.

Ennahda chief Rached Ghannouchi said that the "cowardly" murder was the result of a settling of political scores. The killers "want a bloodbath but they won't succeed," he told AFP.

The four opposition groups blamed Interior Minister Ali Laraydeh from Ennahda for Belaid's murder and demanded his sacking "because he knew he was threatened and he did nothing," according to Nejib Chebbi, leader of one of the blocs.

Belaid's Popular Front and other opposition parties called for a general strike to protest against the assassination.

The United States led Western nations who reacted with dismay at the killing, while Human Rights Watch said the authorities should ensure those responsible were brought to justice.

"There is no justification for an outrageous and cowardly act of violence like this. There is no place in the new Tunisia for violence," US State Department spokeswoman Victoria Nuland said.

German Foreign Minister Guido Westerwelle expressed his "horror" at the attack while French President Francois Hollande condemned a murder that "robs Tunisia of one of its most courageous and free voices."

The violent scenes triggered by Belaid's murder were reminiscent of the uprising that ousted veteran dictator Zine El Abidine Ben Ali just over two years ago, with thousands protesting outside the interior ministry.

Belaid's brother, Abdelmajid, bluntly accused the Ennahda chief of the murder of the 48-year-old leftist leader, who headed the Party of Democratic Patriots, part of the Popular Front.

"I accuse Rached Ghannouchi of assassinating my brother," Abdelmajid told AFP.

The slain politician's wife said her husband had received daily death threats and was murdered before her eyes.

"I saw his blood flowing, I saw his little smile. I saw that they want to kill democracy," Basma Belaid told France's Europe 1 radio.

Belaid had last week accused Ennahda "mercenaries" of attacking his supporters and on Tuesday warned that militias were being created "to terrorise citizens and drag the country into a spiral of violence."

His supporters flooded the streets of Tunis and other cities, including Sidi Bouzeid, birthplace of the 2011 revolution, where tear gas was fired as about 200 people tried to storm the police headquarters.

Protesters torched the Ennahda office near Sidi Bouzeid, ransacked another in Gafsa and set fire to a party office in the northeastern town of Kef.

In Kasserine, on the border with Algeria, hundreds of people calling for "vengeance" took to the streets.

Marzouki deplored the killing in an impassioned speech at the European Parliament.

"This odious assassination of a political leader who I knew well and who was my friend... is a threat, it is a letter sent that will not be received," he said, insisting the murder would not plunge Tunisia into violence.

Belaid, whose funeral will be on Friday after the main weekly prayers, was a populist known for his iconic smile and black moustache.

A lawyer who spoke with the working class accent of northwestern Tunisia, he defended human rights, was jailed under Ben Ali, and was a member of executed Iraqi dictator Saddam Hussein's legal defence team.

Shoes hurled at Iranian president during Egypt visit

From Adam Makary, for CNN

updated 7:06 PM EST, Wed February 6, 2013

STORY HIGHLIGHTS

• This is the first visit to Egypt by an Iranian president in more than 30 years


• Prosecutor's office: Four men are out on bail after allegedly throwing the shoes


• Officials say the men are Salafis, who have accused Iran of financing Shiites

Cairo (CNN) -- During a historic trip to Egypt, Iranian President Mahmoud Ahmadinejad was greeted by a group of men who hurled shoes at him -- a major insult in the Muslim world.

A video posted by the Anadolu news agency shows a smiling Ahmadinejad shaking hands with a crowd of supporters in Cairo late Tuesday when at least one man threw a shoe toward him. Other men also threw shoes at Ahmadinejad, the Egyptian public prosecutor's office said.

"You killed our brothers!" one of the assailants shouted, according to Anadolu. The agency said the man's shoe struck a security guard.

The men behind the attack were four Salafis, the prosecutor's office said.

Salafis follow the Sunni Muslim doctrine and oppose the idea of Shiite Muslims engaging in any political activity in Egypt. They have accused Iran of financing Shiites to spread the Shia doctrine in Egypt, which has a Sunni majority.

The four men were released on bail for 500 Egyptian pounds ($75) each, the prosecutors' office said.

Ahmadinejad's visit to Egypt is the first by an Iranian president in more than 30 years.

He was in Cairo visiting the Grand Sheikh of Al Azhar, Ahmed el-Tayeb. The Al-Ahram news agency said Ahmadinejad also visited the historic Al-Hussein mosque.

The mosque was built in 1154 and it is named after the Prophet Mohammed's grandson, Hussein Ibn Ali. Shiites believe that the Fatimid, Egypt's Shiite rulers, buried his head there and built the mosque as a shrine for Hussein, the first Shiite martyr, who was killed and beheaded in the battle of Karbala in 680.

Why shoe throwing is 'incredibly offensive'

Blizzard could dump 2 feet of snow in New England

CONCORD, N.H. A blizzard heading to New England could make travel nearly impossible and dump up to 2 feet of snow on a region that has seen mostly bare ground this winter.

The snow will start Friday morning, with the heaviest amounts dumped on the region that night and into Saturday as the storm moves through New England and upstate New York, the National Weather Service said.

CBS News weather consultant David Bernard said Wednesday that New York may possibly get snow in the six to 10-inch range. He added that it's a little bit early and that the storm is really going to crank as we go Friday into Friday night.

A blizzard watch for parts of Massachusetts and Rhode Island said travel may become nearly impossible because of high winds and blowing snow.

"This has the potential for being a dangerous storm, especially for Massachusetts into northeast Connecticut and up into Maine," said Louis Uccellini, director of the weather agency's National Centers for Environmental Prediction.

Uccellini, who has written two textbooks on northeastern snowstorms, said Wednesday it was too early to tell if the storm would be one for the record books. But he said it will be a rare and major storm, the type that means "you can't let your guard down."

The storm would hit just after the 35th anniversary of the historic blizzard of 1978, which paralyzed the region with more than 2 feet of snow and hurricane force winds from Feb. 5-7.

No one is wishing for a repeat, but skiers, snowmobilers and other outdoor enthusiasts were hoping for just enough snow to turn around a disappointing season.

The snowmobile season in northern New England started off strong, but after rain and warm temperatures last month, many trails in Maine turned essentially to thick sheets of ice, said Maine Snowmobile Association Executive Director Bob Meyers.

Blizzard on the way

"People got a taste of it, and there's no question they want some more," he said.

Nearly all of Vermont's snowmobile trails opened after Christmas but riding lately has been limited to hard-to-reach mountain areas. Riders hope this week's storm will bring enough snow to cover bare and icy patches.

"I'd say maybe 75 percent of the trail system may be back up and running if we got a good 8-inch storm," said Matt Tetreault, trails administrator for the Vermont Association of Snow Travelers.

Thanks to the ability to make their own snow, the region's larger ski resorts aren't as dependent on natural snowfall, though every bit helps. At Mount Snow in Vermont, spokesman Dave Meeker said the true value of Friday's storm will be driving traffic from southern New England northward.

"It's great when we get snow, but it's a tremendous help when down-country gets snow," he said. "When they have snow in their backyards, they're inspired."

Assuming the snow clears out by the weekend with no major problems, ski areas in Massachusetts also were excited by the prospect of the first major snowstorm they've seen since October 2011.

"We'll be here with bells on," said Christopher Kitchin, inside operations manager at Nashoba Valley Ski Area in Westford, Mass. "People are getting excited. They want to get out in the snow and go snow-tubing, skiing and snowboarding."

Tom Meyers, marketing director for Wachusett Mountain Ski Area in Princeton, Mass., said that at an annual conference of the National Ski Areas Association in Vermont this week, many participants were "buzzing" about the storm. He said the snow will arrive at an especially opportune time — a week before many schools in Massachusetts have February vacation.

"It is perfect timing because it will just remind everybody that it is winter, it's real, and get out and enjoy it," Meyers said.

Still that may be too late for Michael Amarello, director of the Horse Hill 7K snowshoe race, which is scheduled for Saturday in Merrimack, N.H. He said Wednesday that he hadn't yet decided whether to postpone the race, but was leaning in that direction. Race organizers wouldn't have time to mark the course if it's snowing hard Friday afternoon, he said.

"We want snow, but we don't want snow Friday night — we want snow today or tomorrow!" he said.

Armstrong May Testify Under Oath on Doping

Facing a federal criminal investigation and a deadline that originally was tonight to tell all under oath to anti-doping authorities or lose his last chance at reducing his lifetime sporting ban, Lance Armstrong now may cooperate.

His apparent 11th-hour about-face, according to the U.S. Anti Doping Agency (USADA), suggests he might testify under oath and give full details to USADA of how he cheated for so long.

"We have been in communication with Mr. Armstrong and his representatives and we understand that he does want to be part of the solution and assist in the effort to clean up the sport of cycling," USADA CEO Travis T. Tygart said in a written statement this evening. "We have agreed to his request for an additional two weeks to work on details to hopefully allow for this to happen."

Neither Armstrong nor his attorney responded to emails seeking comment on the USADA announcement.

The news of Armstrong's possible and unexpected cooperation came a day after ABC News reported he was in the crosshairs of federal criminal investigators. According to a high-level source, "agents are actively investigating Armstrong for obstruction, witness tampering and intimidation" for allegedly threatening people who dared tell the truth about his cheating.

The case was re-ignited by Armstrong's confession last month to Oprah Winfrey that he doped his way to all seven of his Tour de France titles, telling Winfrey he used performance-enhancing drugs throughout his career and then lied about it. He made the confession after years of vehement denials that he cheated.

If charges are ultimately filed, the consequences of "serious potential crimes" could be severe, ABC News legal analyst Dan Abrams said -- including "possible sentences up to five, 10 years."

Investigators are not concerned with the drug use, but Armstrong's behavior in trying to maintain his secret by allegedly threatening and interfering with potential witnesses.

Armstrong was previously under a separate federal investigation that reportedly looked at drug distribution, conspiracy and fraud allegations -- but that case was dropped without explanation a year ago. Sources at the time said that agents had recommended an indictment and could not understand why the case was suddenly dropped.

"There were plenty of people, even within federal law enforcement, who felt like he was getting preferential treatment," said T.J. Quinn, an investigative reporter with ESPN.

The pressures against Armstrong today are immense and include civil claims that could cost him tens of millions of dollars.

Armstrong is currently serving a lifetime ban in sport handed down by the U.S. Anti-Doping Agency, and today was the deadline he was given to cooperate under oath if he ever wanted the ban lifted.
