As for one-way travelers, I hear you loud and clear and I agree. But this is just another example of how the right hand isn't talking to the left. I'm referring to some of our security agencies, i.e., FBI, CIA and the like, not coordinating with the FAA/TSA. Granted, these such issues (one-way flights, passengers with prostetics) should be handled differently, but overall we all need to accept the fact that we live in a post-9/11 world and, as such, we're going to be subjected to certain things while traveling on commercial aircraft that will make us uneasy from time to time. If you can't take it, drive or take a bus or the train.
Either way, I think if you cooperate you'll be on your way...no harm,no foul.
As for the Patriot Act, yes! I was against it until it was revised and updated and made into the USA Patriat Act.
