Security is misdirected in the new age. Partially because of "Civil Rights," and "Profiling." Basically, The system is it's own worse enemy, because they can't screen who they want to screen, and in the end, it's those people that know the actual rules of how it operates that are going to get through it anyways. Vilgelance is the key.
I hope that they keep the TSA screenings to stictly the airlines. Because all the 135 stuff(and 91) are 99% repeat customers, or recommended customers from another. They won't be the threat, but being vigilent with someone new is always a good idea. Also the fact that most of these airplanes aren't big enough for the mass casualties that the terrorist are looking for, it's even less of a concern.
