<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>&quot;Well trained&quot; in the same sense that the guy making your burger at McDonalds is &quot;well trained&quot;.  And let&#x27;s face it, most of these TSA goons probably <i>would</i> be working at Mickey D&#x27;s if it weren&#x27;t for the TSA.  Not exactly America&#x27;s best and brightest, that lot.  What I can&#x27;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&#x27;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&#x27;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&#x27;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&#x27;d carefully wedged it in between my Nook and a USB harddrive or something, it would never have been found.
