<i>TSA employs a robust security system involving multiple layers of security, both seen and unseen, to protect the traveling public, including a well-trained frontline workforce</i><p>"Well trained" in the same sense that the guy making your burger at McDonalds is "well trained". And let's face it, most of these TSA goons probably <i>would</i> be working at Mickey D's if it weren't for the TSA. Not exactly America's best and brightest, that lot. What I can't see is why anybody is even surprised when this stuff happens.<p>I walked into an airport a year or so ago, headed to Chicago and halfway through the security line realized that I still had my folding knife clipped to my belt. I wasn't going to go all the way back to the car to stow it by that point, so I just jammed it in my bag and figured I'd take my chances. My bag went through the scanner without a peep and I carried the knife on the plane with me.<p>To their credit, the TSA crew in Chicago found it when I went through security on my way back. But the thing is, I wasn't really <i>trying</i> to conceal it. I just jammed it in randomly, making no special effort to obscure or hide it or anything. I really expect if I'd carefully wedged it in between my Nook and a USB harddrive or something, it would never have been found.
