Vigilanteism is among the worst of crimes, because it contributes directly to the breakdown of society. It’s sort of a lesser form of treason, in a sense.

Whatever your views on any political issue, and even if you think someone is a criminal, it is not your role or your right to enforce the law or your views on anyone. Let the police and the courts do their job. And if there’s nothing they can do — then that’s the way it is. “Enforcing” your version of the law only leads to anarchy.
