Much of my objection to the whole opt-out process, other than the screaming and the fact that it will generally cause a TSA employee to go for one of their many approved insults, is that it's open season on your things. Last time I flew, all my stuff ended up on the ground, including my laptop, blackberry, etc. and the TSA employee decided to scold me for the fact that my things fell on the ground after I wasn't allowed to remove them from the belt, and nobody bothered to watch my things.

Someone easily could have walked off with my wallet, my computer, etc. and the TSA's only solution is don't opt out. But I *have* to opt out, since I have prosthetics, or get sent for the scary "resolution pat-down". As I was traveling alone, there's no way I'm getting shuffled off to a locked windowless cameraless room with no witnesses. It'd be really easy to tail me through security and take all my possessions; heck, it's TSA policy to help, since they won't prevent your things from being stolen or, even when asked politely, take them off the belt and isolate them so nobody can take them. TSA-assisted theft...heck, they get to assault you, scream at you, and call you names, why not steal your things, too?
