You should market the rock with a track record like that

To answer the parent question, no not even close.

TSA direct costs, passenger time wasted, flights missed, items confiscated.

All so no bombs on planes. But somehow also no bombs at sports events or music concerts, or on trains or subways, or courthouses or....

So the TSA is either stunningly successful or a complete waste. I'd argue a complete waste, but hey, everyone in a TSA uniform drawing a paycheck us entitled to a different opinion.
