If Szabo violently punched another resident, then he was a menace and I could not fault the coach for acting in defense of another human. The coach was at fault for allowing a person he injured to lie there without calling the police and EMS, instead just driving away. The previously punched ‘resident’ could have collaborated the coach’s story and even if Szabo later died, the coach probably wouldn’t have been charged with anything...might have been even called a hero for dealing with a dangerous drunk. He ran away so now his legal status is in jeopardy!
Yes, I agree it was a mistake to not call authorities and stick around when it was probably quite obvious that the man was badly hurt.
