Get a life! The events of Sep 11 had absolutely nothing to do with checked baggage! The great American chicken is alive and well. The only thing matching baggage and customers and xraying all baggage will do is slow down system even more. It will be 4-5 hr checkins for flight. I am not willing to put up with that. I've flown 60,000 miles since sep 11. If you are afraid. Don't fly. Just don't expect the frequent flyers to share your fears or put up with your "the sky is falling mentality."
Life is full of risks. Getting up in the morning is a risk. I assume you do get up.
