Very well put Avira.
The only thing , I have to add is it reminds me of George Zimmerman, there’s a bit of a hole in the system. You have loser waanabe-cops who get involved in a confrontation, naturally they can’t actually fight, so when they are losing, they can fall back on their gun and (legitimately) claim self defense .
He is no hero.
Though I doubt he’s walking away rich he will be sued by the victims and will be swamped with legal fees for some time
