Based on this incident I predict congress will act. This is low hanging fruit for members on both sides of the aisle to look good to their constituents. Please remember that more than half of congressional representatives are ex-attorneys. I predict a passenger bill of rights law that will include:
1) no involuntary bumping for crew movement
2) required cash (not voucher) compensation for involuntary bumping - possibly as much as $10,000.
3) prohibition of law enforcement involvement for non-safety related actions.
Congress gets involved when industries fail police themselves and abuse the general public. This incident was like throwing chum into the middle of a school of sharks. The feeding frenzy will commence.
