Yahoo, Feds Battle Over E-Mail Privacy
From Threat Level:
Yahoo and federal prosecutors in Colorado are embroiled in a privacy battle that’s testing whether the Constitution’s warrant requirements apply to Americans’ e-mail.
The legal dust-up, unsealed late Tuesday, concerns a 1986 law that already allows the government to obtain a suspect’s e-mail from an ISP or webmail provider without a probable-cause warrant, once it’s been stored for 180 days or more. The government now contends it can get e-mail under 180-days old if that e-mail has been read by the owner, and the Constitution’s Fourth Amendment protections don’t apply.

Video: Boeing 747 Withstands Simulated What-If Underwear Bomber Blast
From Popular Science:
The bomb blast was meant to gauge what might have happened if the Flight 253 suicide bomber succeeded.
An explosion aboard Flight 253 on Christmas Day would not have crippled the Boeing 747, according to a recent test that simulated the success of would-be bomber Umar Abdulmutallab. Only the bomber and passenger next to him would have died, the BBC reports.

My Comment: I am sure that Al Qaeda is appreciative of this test .... it means that if they wish to do this in the future they will have to pack more explosive.

Airports Could Get Mind-Reading Scanners
From Live Science:
WeCU Technologies is building a mind-reading scanner that can tell if a given traveler is a potential danger - without the subject's knowledge. WeCU Technologies (pronounced "we see you") is creating a system that would essentially turn the public spaces in airports into vast screening grounds:.
"The system ... projects images onto airport screens, such as symbols associated with a certain terrorist group or some other image only a would-be terrorist would recognize, company CEO Ehud Givon said.

Quartz Rods Could Provide Instant Bomb Detector
From New Scientist:
A CHEAP artificial nose promises to make it much easier to detect the explosive triacetone triperoxide. The device could be installed in the doorways of buses, trains and airports to sound an alarm if someone carrying TATP crosses the threshold.
Attention started to focus on TATP following its use in the 7 July 2005 bus and tube bombings in London, and the attacks on trains the previous year in Madrid, Spain. The explosive can be made using easily obtainable domestic chemicals and has explosive power similar to TNT.

Airport Security Unlikely To Spot Hard-to-Find Weapons
a new study found. Credit: StockXpert
From Live Science:
When airport screeners don’t expect to find a gun in your bag, they likely won’t, suggests new research that shows that when people think something will be difficult to find, they don't look as hard as when they think they're likely to see what they're searching for.
Call it the needle-in-the-haystack effect: Humans aren’t adapted to finding rare things.
"We know that if you don't find it often, you often don't find it," said cognitive scientist Jeremy Wolfe of Harvard Medical School. "Rare stuff gets missed."

Crack New Scanner Looks For Bombs Inside Body Cavities
From The Danger Room:
The “underpants bomber” has renewed calls for new and more invasive security measures. Already, there’s a push to install scanners that show travelers’ naked bodies through clothing, using either millimeter wave or backscatter X-ray imaging. But even those scanners might not have caught the terrorist who nearly brought down Northwest flight 253.

Can Full-Body Airport Scanners Harm You?
From CNET:
Since explosive materials were sneaked onto a U.S. domestic flight on Christmas Day, full-body scanning machines are far more likely to make their way to security lines at your local airport, even though they might not have detected said materials.
While the Transportation Security Administration already has 40 such devices in place, it just bought 150 to be placed in U.S. airports and says it plans to buy 300 more (they go for $170,000 apiece). On Wednesday, the Netherlands announced that these scanners would be used on passengers for all flights out of Amsterdam to the U.S., and there is talk of scanners in Nigeria as well.
My Comment: They better find the answers soon before we start spending billions of dollars for this tech.

How To Find Hidden Explosives At Airports
From Technology Review:
We already have the technology for discovering hidden explosives, but it could lead to long lines.
The bomb that Umar Farouk Abdulmutallab reportedly tried to set off as his flight neared Detroit on Christmas could have been detected using existing screening technologies, had they only been used. Not only could the explosives have been spotted using back-scatter X-rays or millimeter wave technology--which can see through clothes--invisible traces of the explosive could have been detected using chemical sensors. But both technologies, if used to screen all passengers, would lead to long lines at airport security checkpoints.

Are New TSA In-Flight Restrictions Pointless?
From Discovery News:
On Christmas Day, Nigerian wannabe terrorist Umar Farouk Abdulmutallab set fire to his pants on Northwest Airlines Flight 253 as it was on its final approach to Detroit Metropolitan Airport.
The fire was sparked when Abdulmutallab failed to detonate a homemade mix of explosives that were carried on board the aircraft concealed in the crotch of his underwear.

Would You Be Happy To Take The 'Naked' Body Scan?
From The Daily Mail:
Fears over airport security could leave millions of passengers facing the indignity of a 'naked' body scan and paying higher fares to fund it.
Hi-tech body scanners can see through clothes to detect hidden weapons or explosives such as those used in the failed Christmas Day plot.

Airport Security: Why It Failed
From Live Science:
Airport screening procedures failed for many reasons to catch the Nigerian man who aimed to blow up flight 253 as it approached Detroit. Scanners that might have spotted the explosives are not fully deployed, and even at airports where they exist, the scanners aren't used on all passengers.
Bottom line: No system will likely prove foolproof, experts say.
Investigators say 23-year-old Nigerian Umar Farouk Abdul Mutallab hid an explosive device and the chemical explosive PETN on his body while traveling from Amsterdam to Detroit aboard the Delta flight on Christmas day.

New, Terrifying, No-Electronics U.S. Flight Security Rules?
From CNET News:
That failed terrorist attack Friday might make international flights a whole lot less enjoyable. Passengers are reporting that new restrictions are in place, and their severity varies flight to flight. Among the reports: No electronics allowed.
Update: According to a tweet from industry analyst Charlene Li, here's the situation:

New Advances In Airport Screening Technology Will Deter Future Terrorist Attacks

Holiday travelers: Sick of waiting in long airport security lines? T-rays are here to help.
Using several new advances in T-rays, or terahertz radiation, airport scanners could soon determine if a vial of white powder in a suitcase is common sugar or illegal drugs.
Scientists at the Massachusetts Institute of Technology, at Rice University, in Europe and elsewhere have independently undertaken research to make it dramatically easier and cheaper to produce, amplify and direct T-rays.

Tunable Terahertz Lasers Could Allow Airport Scanners To Chemically Analyze Substances
From Popular Science:
A new way to tune the width of terahertz quantum cascade lasers heralds a breakthrough in airport scanning and much more.
If Superman saw in terahertz radiation, he could do more than just peer through clothes and the human body. The Man of Steel might also be able to identify the chemical difference between a benign powder or an explosive tucked away inside a vial within a suitcase -- assuming that he could somehow tune his vision.

Airport Body Scans Reveal All
From Live Science:
New airport security scanners could become a popular alternative to body searches, but have also prompted some privacy concerns.
Whole-body imaging technologies can see through clothing to reveal metallic and non-metallic objects, including weapons or plastic explosives. They also reveal a person's silhouette and the outlines of underwear.
That hasn't stopped security officials from implementing them. The U.S. Transportation Security Agency (TSA) started using whole-body imaging at six airports this year, and plans are in the works to expand it to airports in several more U.S. cities later this year.
