Abuse the authority? Nonsense. This is the sort of thing that security ~should~ be doing. Too much time and energy is spent trying to keep “things” off of airplanes when it’s not the “things” that are necessarily the problem. It’s the terrorist ~people~ that need to be recognized, not the nail clippers.
It’s not the gun. It’s the shooter.
I think we’ve gone way overboard with TSA security. We should leave it to the people and the private sector. Our federal government is stupid and way too incompetent to be left in charge of such an important issue.
