TSA John: Welcome to Flyertalk!

I know that my underwire will set off the detector, so I wear a tank top with a shelf bra when I fly. Likewise, I have a pair of shoes without metal that I always wear. I don't like getting felt up when I fly nor do I like getting my bags rifled through. I'm sure you guys don't enjoy it any more than I do. What other things can I do when I fly to avoid unintenionally triggering a search? I recently learned that a keychain can look like the detonator of a grenade, so I'll be mindful of that when I pack.

Another concern I have is that if my bag is searched or my laptop is swabbing, I want to be right there. I don't like the thought of someone else grabbing my laptop off the belt, and taking it aside for swabbing unless I am watching. I also don't like the thought of someone digging through my bag unless I am right there to make sure they put on clean gloves and so I can see exactly what they touch (cause if they touch my undies, those go straight in the trash). What tips do you have so that we can all deal with this with a minimum of pain?
