If you think about it long enough.... maybe it begons to make sense.
When I was in college, this idiot was waving around what looked like one of the little plastic trinket guns you used to get get out of Crackerjack boxes, and he fired it. It misfired, but a flaming piece of debris came out of it. Nobody hurt.

Maybe the "highly qualified, well trained" minimum wage and intelligence security guard (?) put 2 and 2 together, and came up with 3. (He don't need to think, he got RULES and PROCEDURES.)

Give a minimal intelligence some authority, and right away it will be abused.

Like the airport "guard" that used his authority (as he supposed) to get improperly familiar with a retired Marine Colonel's lady. The Colonel punched him out, but guess who was in trouble? Right... the Colonel.

We hear the horror stories, and I HATE L.A. International. But, my last experience with a TSA employee was professional, pleasant, and fast.
