I think you may be missing the point that it doesn't matter if a pilot is high or low risk; if he or she is about to take control of an aircraft, because that's what's on the roster, there's no point in searching him/her for weapons or means of suicidal destruction.
I'm not at all worried about the pilot's susicidal leanings. The greater risk, minimal as it may be, is that the pilot will subcomb to girl friend pressure and take through some lotion for her travel use when I can not. Then of course it later turns out that the girl friend intends to use the lotion for nefarious purposes, against another flight so we all lose.
OK so I admit, I'm not going to win any arguments on this board, but neither will the pilot community prevail in front of the media or the public unless they act in concert.
