leaving crazy people to run around the streets after multiple cases of them brutally assaulting people is the problem. you can't apologize for this neglect of justice. half a dozen people at least were victims of this maniac before he finally went the whole way. there was plenty of chance to prevent it.

so, yeah, it is apologetics for murderers. everyone who thinks its ok to punch someone is under suspicion when they do it for random, crazy reasons. there was a marketing campaign in australia years ago "one punch can kill" it's literally true. one slash on the right part of someone's body also can open a major blood vessel or artery that leads rapidly to bleeding out as well. even a punch can cause this in some cases though that's pretty rare unless they are a hulking monster like this case.
