That’s nuts. Even if you were correct about that, and I’m not admitting any such thing, it isn’t how people work. If the state doesn’t provide justice, then the mob will.
"Justice" is an incredibly malleable idea that is largely shaped by what people are told. Until very, very recently, nobody gave a fuck about serial killers, or even knew they existed. If the hype stopped, there wouldn't be any mobs to worry about.
