"it was more like they were trying to apprehend/disarm a killer."

You must've been watching something else but in the videos I posted you can see multiple attackers lung at him with a molotov, kicks, punches, a skateboard and a handgun. They are probably prone to thinking they're invincible when attacking with a mob and I don't believe there is a decent case for a murder charge to stick, that only sounds like wishful thinking on your part.
