The "naked picture machines" you are talking about are no longer used. They haven't been for some time. Why? Because people spoke out about them and their general ineffectiveness (sadly, you are more worried about people seeing your dick than the fact that the machines couldn't identify a knife carried on the side). It doesn't change the fact that security is needed at airports. It also doesn't make it okay to yell "BOMB" when you're all pissy about getting searched.
First, backscatter machines are still in use in some airports. Second, the backlash against them is entirely justified. They are X-Ray devices. The company that manufactures them flat-out made up the studies that claim they aren't X-ray devices. Frequent air travelers (and I used to be one) were / are being exposed to absurd amounts of radiation. I always, always, always, opt for the pat down.
And yes, as he points out, Michael Chertoff, the former head of DHS, joined the board of the company that manufactures those machines shortly after DHS put in a purchase order for quite a few of 'em.
Aldon Smith is still a moron.
