Not to hijack too much, but this is the reason we have TSA in the first place. The airlines don't want to take responsibility for anything that they can feasibly pass off to government (and blame if something goes wrong). I agree that it would solve the problem but it would never happen. The airlines love TSA, because TSA lets them cover their butts if anything ever did (does) go wrong.
