The NYPD's X-Ray Vans (theatlantic.com)
An anonymous reader writes: A few years ago, we heard tales of vans outfitted by the U.S. government to hold giant X-ray scanners, which they'd use to drive around and inspect vehicles. Now, it turns out similar vans have made their way to police departments, including the NYPD. The police are unwilling to explain (PDF) how they're used, or how often. "A state court has already ruled that the NYPD has to turn over policies, procedures, and training manuals that shape uses of X-rays; reports on past deployments; information on the costs of the X-ray devices and the number of vans purchased; and information on the health and safety effects of the technology. But New York City is fighting on appeal to suppress that information and more, as if it is some kind of spy agency rather than a municipal police department operating on domestic soil, ostensibly at the pleasure of city residents."
Ah yes, the lovely liberal capital of the US east coast, Deblasio and Schumer heaven, spying on their liberal base! WOW, color me SHOCKED!
Adding to this, if their platforms are covert vans, that implies the imaging systems are backscatter devices, meaning they are detecting a reflected signal and not a transmitted one. To the parent, x-rays won't penetrate metal, but reflect. However if they are imaging things like people, and since x-rays aren't deflected well by us (except for our bones), then they are having to pump more radiation out of their aperture to collect enough reflected signal for an image than they would if they (like medical x-rays) were making a transmission measurement.
Of course if word got out that they were cooking people with ionizing radiation in the name of national security, the terrorists will have won.
They are, indeed, backscatter devices. See source here.
The summary is actually wrong in claiming that these vans are just now making their way to police departments. According to this link, the NYPD acknowledged using these vans at least as early as 2010. I'd really like to know how they've been used over the last five years or if there's any evidence of any additional security being provided from this surveillance.
The police feel much more secure. Does that count?
Sleep your way to a whiter smile...date a dentist!

It's not. This has already been decided by the courts.

> Kyllo v. United States, 533 U.S. 27 (2001), held that the use of a thermal imaging, or FLIR, device from a public vantage point to monitor the radiation of heat from a person's home was a "search" within the meaning of the Fourth Amendment, and thus required a warrant.
This. Cops were dumb enough to give themselves testicular cancer by constantly irradiating their testicles back when laser guns first came out (by holding the gun between their legs while it was on). They will certainly be dumb enough to blast people with much more radiation than necessary with these devices. Cops are, after all, selected for low IQ.. Let's give them a ray gun that can give people cancer! What could possibly go wrong?
Seven puppies were harmed during the making of this post.
The Supreme Court ruled the government could not use nascent IR scanners to "see" through house walls without a warrant, and that's a freaking passive scanner.
An active one like X-ray is a clear and blatant violation. This one is not even close. These people should literally be sent to jail.
