It is pretty difficult to train "common sense", but it needs to be a requirement for a screening job. Perhaps consistency as well as more traning for the security inspector? Why can one have a metal fork but only a plastic knife? Why can't I have the midget nail clipper file, but I can keep the American Flag Pin on my coat? During the "extra random" search one is required to empty the pockets after beeping (pocket change only) and then ordered to return the change to the pocket. The wand is again run down the back and inside of the same leg. The security matron then demands to know exactly what that noise is . . .gee, perhaps the coins one was just ordered to put back into the pocket? We had an additional search by United Personnel several weeks ago @ Pittsburgh and had a very professional and complete search . . .however, the airline SECURITY PERSONNEL @ SNA were rather unreasonable and unknowledgeable.
