Flyers have rights in re: (in)voluntary bumping. But current rules don't address situation where already on board. These rights clearly need to be expanded to cover more situations and also protect passengers against use of force. Airlines need stronger regulations for how they deal with overbooking. Also, we need better mandatory training for airport security personnel, emphasizing de-escalation. This cannot be allowed to happen again. https://www.transportation.gov/airconsumer/fly-rights
