Nobody is "supporting" the staff in question; you're just making that up. It's a huge reach and a sloppy argument.

Unruly passengers represent a clear danger to the safe operation of flights. They cannot be tolerated. Period, paragraph. There is, obviously no such danger posed by the actions of airport security, on the ground, and in any case, airlines have no jurisdiction over those people. They absolutely do have jurisdiction over passengers, though.

If you get on a plane you agree to fucking obey the directions of flight staff. It's federal law.
