Well, I may, or may not, still be on the no fly list, but I was not too surprised to find the document that follows when I opened my suitcase after flying into town last night.
I suppose this kind of surveillance might detect a bomb, though I tend to suspect that, like the no fly list, this is really just the Theater of Fear. There was no evidence that anything in the suitcase was disturbed. I don't lock, so they didn't have to break in. I hope they found my dirty underwear and socks fascinating.
It may have been a good thing that I threw the book I'm currently reading, When Victims Become Killers by Mahmood Mamdani, in my carry-on.
