Q: How realistic are movies that show people breaking into vaults?

A: Not very! In the movies it takes five minutes of razzle-dazzle; in real life it's usually at least a couple of hours of precision work for an easy, lost combination lockout.

Q: Have you ever met a lock you couldn't pick?

A: There are several types of locks that are designed to be extremely pick-resistant, as there are combination safe locks that can slow down my efforts at manipulation.

I've never met a safe or lock that kept me out for very long. Not saying I can't be stumped. Unknown mechanical malfunctions inside a safe or vault are the most challenging things I have to contend with and I will probably see one of those tomorrow since you just jinxed me with that question.

Simon and his colleagues used a combination of direct, high-resolution chemical techniques to determine that the melanin had been preserved. The researchers also compared the chemical composition of the ancient squid ink remains to that of modern squid ink from Sepia officinalis, a squid common to the Mediterranean, North and Baltic seas.

"It's close enough that I would argue that the pigmentation in this class of animals has not evolved in 160 million years," Simon said. "The whole machinery apparently has been locked in time and passed down through succeeding generations of squid. It's a very optimized system for this animal and has been optimized for a long time."

As usual, you can also use this squid post to talk about the security stories in the news that I haven't covered.

Although the plot was disrupted before a particular airline was targeted and tickets were purchased, al Qaeda's continued attempts to attack the U.S. speak to the organization's persistence and willingness to refine specific approaches to killing. Unlike Abdulmutallab's bomb, the new device contained lead azide, an explosive often used as a detonator. If the new underwear bomb had been used, the bomber would have ignited the lead azide, which would have triggered a more powerful explosive, possibly military-grade explosive pentaerythritol tetranitrate (PETN).

Lead azide and PETN were key components in a 2010 plan to detonate two bombs sent from Yemen and bound for Chicago—one in a cargo aircraft and the other in the cargo hold of a passenger aircraft. In that plot, al-Qaeda hid bombs in printer cartridges, allowing them to slip past cargo handlers and airport screeners. Both bombs contained far more explosive material than the 80 grams of PETN that Abdulmutallab smuggled onto his Northwest Airlines flight.

With the latest device, al Asiri appears to have been able to improve on the underwear bomb supplied to Abdulmutallab, says Joan Neuhaus Schaan, a fellow in homeland security and terrorism for Rice University's James A. Baker III Institute for Public Policy.

The interview is also interesting, and I am especially pleased to see this last answer:

What has been the most effective means of disrupting terrorism attacks?
As with bombs that were being sent from Yemen to Chicago as cargo, this latest plot was discovered using human intelligence rather than screening procedures and technologies. These plans were disrupted because of proactive mechanisms put in place to stop terrorism rather than defensive approaches such as screening.
