I recently flew from Chicago (ORD) to San Francisco on AA. I got to the hotel only to discover that my bags had been relieved of some new computer software and games I had bought. Obviously, I don't know whether it was the TSA or the baggage handlers who had the sticky fingers, but obviously my faith in the entire security system is somewhat compromised. Normally, my bags get checked by TSA and they kindly leave a note saying as much (and breaking the TSA approved locks in the process).
Viva airport security!
