Why don't they just install a background behind the subject that produces a checkerboard pattern? This is exactly why programs like Photoshop use a checkered background to make it trivial to detect transparency in your images. Wouldn't that render the exploit this guy found obsolete?
We've put incomplete tech and massive room for human error in between people and air planes. It's worse than security theater, it's a full digression in our our actual security. We're actually less safe than we were 15 years ago. If this man's video is to be trusted, it's now easier than ever to bring a box cutter onto an airplane. Boggles the mind.

I'll let you figure out why building a backing that is made up of different materials that reflect radiation in a checkerboard pattern won't work.
Body scanner proven ineffective video http://www.youtube.com/watch?v=idICUSiGcqo
Body scanner has 54% false positive rate https://www.propublica.org/article/sweating-bullets-body-sca...
Cost of the body scanners http://www.advicegoddess.com/archives/2012/03/07/what_tsa_se...
Some pretty interesting numbers here:
"Of these, 18 airports handle fewer than 1,000 passengers daily but were equipped with 21 scanners at an estimated installed cost of $7.3 million to screen 9,538 passengers per day."

I'd love to know that too. I just threw in $100 (via the donation button on the top right of the linked article), but I'm glad to donate more if he needs it. I really wish I had time to tilt at this particular windmill, so I'm very grateful that this fellow is being so relentless.
Thank you for that! The cost in filing fees, printing, and mailing for SCOTUS I estimate to be near $2K. If it's accepted, I need to travel to DC for oral arguments. All this in addition to dozens (or more) hours of missed work in order to research, write, and handle things. Even if I got no donations, I would self-fund this suit, so no worries about donating more... anything anyone wants to contribute is much apprec…
What are the estimated costs of getting a lawsuit to the Supreme Court?

Be sure to read the TSA's official response on their blog. [1] The comments there are priceless. [1] http://blog.tsa.gov/2012/03/viral-video-about-body-scanners....
What morons, they use the word "interwebs" in the first sentence to make themselves look hip to the internet. The whole tone of this blog post though really rubs me the wrong way. it comes across as a post from defensive asshole teen who was caught looking like a fool, as opposed to a federal agency funded with BILLIONS of free money they take from the citizens which they spend in ways which are completely unaccounta…

How many failing bridges could have been replaced with the $60 billion we've spent on the TSA? Those would be some nice skilled jobs for people dropping out of our flagging manufacturing sector...

Install a background? Photoshop? You do realize that the backscatter machines aren't taking a picture right? There isn't a "background" to change. It's basically an X-ray machine, throw some radiation, see what bounces back. I'll let you figure out why building a backing that is made up of different materials that reflect radiation in a checkerboard pattern won't work.
Uh. Why won't it work? From what I recall of the images, they're sort of gray-scale. The brightness of a body drops off as it falls away from the camera (i.e. the outline of your body is a darker gray than, say, your forward-facing bellybutton region), since, presumably, as we wrap around to the sides of your body, more energy is bounced out to the sides than to the 'camera'.
So, I assume it's depicting the amount of radiation reflected back to the 'camera', right? So, if you make a checkerboard background of materials that bounce differing amounts of energy back (either due to composition of the tile or its angle), why wouldn't it work?
