Inside a Full-Body-Scanning X-Ray Van

Velcroman1 writes "In August, Slashdotters learned that full-body scanners were roaming the streets in vans: 'The same technology used at airport check points, capable of seeing through clothes and walls, has also been rolling out on US streets where law enforcement agencies have deployed the vans to search for vehicle-based bombs. Fox took a ride in one of the $800,000 vans, videotaping the entire event — and continues the debate about security, privacy, and health risks."

    Come on, tell me, what's the real purpose of this stuff? 8 million flights without a successful terrorist attack since 9/11. All attempts either simply failed or were prevented using pre-9/11 technology, yet we still get these naked body scanners.

    Now we also need them roaming the streets? "Hey Joe, hottie on your six, make a turn and flip the switch boy, let's see what she's got!". Anything else doesn't come near a justification.

      The interesting thing is that the government has decided to do everything in its power to ignore that risk/reward ratios. they want to get rid of all of something, which is silly, they should want to get it down to a certain, acceptable level, then focus time and money on something else.

People will stand up and fight, and no pilot will open the door because someone is threatening to hurt the flight attendant.. Everything else is just security theater.

  2. Dumb to use away from points of entry by explosivejared · · Score: 3, Insightful

    It's definitely a dumb idea to have these things just roaming the streets, and that's without even considering the privacy concerns. It's absurdly hard to actually identify items that only rarely occur, say weapons, in samples like this. The human eye just isn't that good at it. It gets worse the more samples you take. The only place I can see for this is scanning at the border where people being smuggled in would be pretty obvious. At the border, a search like this makes sense since by law it's necessary to declare many items that you bring into a country. Otherwise, not only is it mostly a waste of time, but a dead ringer for an unreasonable search. The article was light on just how prevalent their use is outside of ports and points of entry, so it's hard to say if there's any serious danger to the average person on the street. Also, health concerns are probably overblown. If the dose is in micro Sv, that's a small fraction of the regular background dose.

    This blurb in the article basically says it all...

    "Using the ZBV vans over the past couple of years, we've gotten over a thousand seizures and 89,000 pounds worth of narcotics, approximately $4 million worth of currency, and we've also uncovered 10 or 11 undeclared aliens within vehicles," said Patrick Simmons, Director of Non-Intrusive Inspection at Customs and Border Protection. "Again, we don't purposely scan for people, but if they're in there hiding, the ZBV will be able to spot them."

    While many dismiss / marginalize the threat of the drug war on people's freedoms, it's happening nevertheless. For example, there was a time when local police busting down doors was virtually unheard of - now it's common practice in all sorts of situations. Another is that people are now subjected to all sorts of demands, such providing government id / signing a form, to buy over-the-counter cough medicine. All in the name of the drug war - which is really a war against citizens.

    For anyone who believes use of such technology to search people / private property will be ruled unconstitutional, think again - drug sniffing dogs are often allowed to search one's private property, such as one's vehicle, that's accessible from the street despite no "contraband" being in plain view.

    One can practically count on such vans roaming the streets all throughout the U.S. in the near future "for your protection", but of course, much of the time, that won't be the real motivation.

      The difference with a drug dog is that they're not searching your car, they're searching the ambient air. It IS in plain "veiw" (nasally) to them. The car is basically leaking drug particles all over the place, which is glaringly obvious if you have the wetware to detect it. This is completely different from scanning the inside of a person/vehicle/house.

      The cop could lie, and the dog could be trained to lie, which potentially subjects everyone to unacceptable harassment. With machines honesty is a generally higher--though buggy closed-sourced devices aren't very trustworthy. The problem is really the government prohibition of the possession of certain molecules. This is the invasion of liberty that all searches just make more evident. Even if we are talking about 100lbs of plastic explosives, it's not clear that cost/benefit ratio (for us, not the government) justifies making possession a crime.

      Slippery-slope comes to mind. Since when did one relinquish their rights at the airport? -it wasn't always that way. And furthermore, such searches are now becoming routine on long-haul passenger trains (ie. Amtrak) and buses (Greyhound) too. And even one's own vehicle at some select locations, such as tunnel entrances.

      You're assuming the government will protect one's rights - sadly, that's often not the case. Watch some episodes of COPS for a reality check on how policing really works in the U.S. - the police state is already here.

      In addition, home monitoring technology has greatly improved and hence, the number of people under court supervision is rapidly expanding so, in turn, there's little in the way of stopping the police state of expanding ... it's easily conceivable that upwards of 10% of the adult population could in the next decade or so be under some court mandated supervision.

      Digressing, but don't think for a second, that the courts alone are going to stop technology, such as the vans, from being used for searching people / property - only a revolution, or more ideally, some power-elites, choosing to put freedom of citizens ahead of profits and power will.
