Regardless, please explain how checking anyones ID (with the exception of the aircraft operators credentials) contributes to the safe conduct of a commercial aircraft flight.

I guess if an ID was thrown really hard the narrow edge might make a paper cut but then they would be considered a weapon and confiscated with my water.

I thought the purpose of screening was to ensure no weapons, explosives or incendaries made it onto the aircraft.

Isn't all the rest of the play nothing more than poor theater?

I say it is!!
