Don't forget that they aren't even able to find the dangerous items. Their system frequently allows box cutting razor blades onto airplanes. How do I know? It happened to me: http://bit.ly/if5XDR after experiencing a traumatic "enhanced" pat down procedure.

After my incident I went to both of my Senators and my Congressman (in person) and recounted my story. I also followed the TSA procedures for reporting civil abuses, which incidentally was a completely worthless excercise.

Their written response to my Congressman's letter to them was, "We followed procedure".
