you do know they are trained to restrain unruly passengers right? no? how about that they are "the police" in the air figuratively speaking? no again? seems like someone else needs to think before they say something.

laws would need to be changed though to allow a passenger to be confined to a chair or holding cell. as it stands now airlines can only restrain body parts. that probably plays a big part into a pilot's decision on getting rid of an unruly passenger by making an unscheduled landing.
