Aren't you committing an "argument from consequences"?

The argument most people are making is that the TSA is security theatre, and they're not stopping any bad guys.

I don't think anyone would argue if the TSA's methodology had any basis or evidence of efficacy. Usually the stories take on some ridiculous aspect: Someone has handled some chemicals that set off the detector, and they're interrogated for twenty hours - can't they just check the luggage for a bomb?
