A not-very-PC lol-pic for haamel, if he hasn't defriended me over my TSA ranting ;)
And for the rest of you, here's a nice li'l story about the Al Qaeda cavity/suicide bomber who recently almost killed a Saudi prince:

And one from "everyone's favorite" Fox News about explosives inside breast implants that British agents supposedly have discovered:

Neither nekkid-scans nor "enhanced" groping would be able to detect either method.
But don't worry; those TSA agents screening you are always "properly and carefully trained" -- NOT.
