yes. they should be tried for beating the man and looting his car.
whole situation was avoidable. who chases down a gang of hyped up teenagers over littering? one of the kids threw a bottle and now this guy has injuries, severe property damage and a bunch of his possessions stolen. he chose to escalate the situation. don’t escalate. move on with your life. especially if you have all your belongings in your car because you’re moving.
