Naked body scanners are useless

A demonstration of a full body-scanner on a German TV show.

It picked up a cellphone cell phone, Swiss Army knife and microphone on the scanee. But don't worry. The precious bomb components would have made it safely on board.

Outside, they show the scanee's payload.

Even though it's all in German, it's easy to follow along. You may even recognize a few works since English is just the bastard child of a German mother and French father.

I can't tell exactly what method of scan they are using, but it looks noticeably less detailed than the images produced by the demonstrations I have seen lately.

This is the only video I can think of off-hand that shows the *cough* details (yes, I submitted it)... the scans are at the 1-minute mark of the video.

So if I take a Nissan GT-R to a dyno, it should get 485 HP despite variables, like an improper test. If it can't achieve this without tires, then the system is flawed, and not the test.

If you've ever been through airport security, you know that you must remove any jacket. Also, if this technology were adopted by the TSA, you know that the bureaucracy would be very very clear in training how to use it effectively.

If you cannot pragmatically prove your system works, then it does not work.
Whether the test was flawed or the variables were not well planned for it is clear that this failed.

Should never have made it out of QA.

Not only does it not work, but it gives a false sense of security. I highly doubt this scanner is more effective than traditional methods but it does put even more emphasis on equipment at the expense of people. Pay your staff better, attract good quality people to the work and you'll be safer but the public can't SEE better training, they can SEE high tech whiz-bang gizmos.

The real reasons why this system is being adopted are:

1) It gives a sense of security to dumb passengers.

2) It costs a lot of money. The company making them will make a lot of money. They've already borrowed against this future earning potential to bribe lawmakers. Ahem I mean 'lobby' lawmakers.

Big business wins at the expense of everyone else, that's the system.

But jokes aside, I've had one event burn the realization into me that (airport) security is a people problem, not a technical problem (until we get real AIs with a creativity chip). San Francisco Airport, February 2002. Me a non US citizen, dressed all in black, longish hair and the infamous "ZZZ" on the ticket.

First, standard screening: the security people (mexican) are bitching at their supervisor (thai) in a strange mix of english, spanish and something I didn't get and I got the overall impression that they had to use hands and feet just to be able to communicate in broad terms. The guy giving me a rub-down with the wand didn't notice that the wands battery fell out until I pointed it out to him. He did the wand-to-wrist-watch test and failed to notice the missing beep. Just going through the motions, not really caring about the rest and seemed pretty harassed by just about everything

Second screening at the gate: I put my jacket to one side and my carry-on to the other. While I was more or less enthusastically frisked by another minimum wage security person, another was puzzeling if the math books he found in my carry on were a threat to national security. Here's the kicker: my jacket was pretty much worn out with holes in the pocket so you could reach all the way around inside. Perfect hiding spot of just about anything nasty and would warrant a closer look, right? Except noone even bothered to look at the jacket. Not once.

I can tell you, I felt very safe getting into my seat after boarding.

Ever since then I'm a fully paid up subscriber to Bruce Schneiers message that making people feel secure by doing blatant things with their rights isn't the same as making people secure by actually doing your job. So please, dear politicos and airport owners, pay the security people at the airport more than minimum wage. Give them job satisfaction and an incentive to do their job right. And quit wanking over cool tech stuff you saw in early 90s Schwarzenegger movies that just doesn't work in real life.

Indeed the real thing shows way more detail
