From The Atlantic:
This past Wednesday, I showed up at Baltimore-Washington International for a flight to Providence, R.I. I had a choice of two TSA screening checkpoints. I picked mine based on the number of people waiting in line, not because I am impatient, but because the coiled, closely packed lines at TSA screening sites are the most dangerous places in airports, completely unprotected from a terrorist attack — a terrorist attack that would serve the same purpose (shutting down air travel) as an attack on board an aircraft.
Agents were funneling every passenger at this particular checkpoint through a newly installed back-scatter body imaging device, which allows the agency’s security officers to, in essence, see under your clothing. The machine captures an image of your naked self, including your genitals, and sends the image to an agent in a separate room. I don’t object to stringent security (as you will soon see), but I do object to meaningless security theater (Bruce Schneier’s phrase), and I believe that we would be better off if the TSA focused its attentions on learning the identity and background of each passenger, rather than on checking whether passengers are carrying contraband (as I suggested in this article, it is possible for a moderately clever person to move contraband through TSA screenings with a fair amount of ease, even with this new technology).
In part because of the back-scatter imager’s invasiveness (a TSA employee in Miami was arrested recently after he physically assaulted a colleague who had mocked his modestly sized penis, which was fully apparent in a captured back-scatter image), the TSA is allowing passengers to opt-out of the back-scatter and choose instead a pat-down. I’ve complained about TSA pat-downs in the past, because they, too, were more security theater than anything else. They are, as I would learn, becoming more serious, as well.
