Everyone should note that they called law enforcement and law enforcement used physical force on the passenger.

Should the airlines be prevented from ever contacting law enforcement? Is law enforcement not responsible for their own actions after the airline asks them to do something?

The should not contact law enforcement when someone refuses to leave the plane because it's overbooked.

If someone is actually causing a problem or is somehow dangerous, then yes, by all means, call the police.
