That is exactly why more and more people are actually choosing to have their luggage shipped ahead of time and afterwards by shipping companies, instead of dealing with crap like that.
I had TSA steal a very expensive swiss army knife out of my checked bags once. I know they took it because I put it, along with a leatherman, into an inside pocket of the bag right before the bag drop for screening by TSA, and then it came back with the note saying they screened it, the leatherman was in there, but the very expensive swiss army knife was awol!
