Not sure where this was filmed, but vigilante punishment sometimes is required. I would have preferred a legal process to try and convict by his peers with due punishment. That said, IF the criminal was caught red-handed without any reasonable doubt of his innocence then the punishment rendered should be held accountable by the "executioner" if and when any legal authorities appear.

That looks like a brutal beating and if he survives, I bet he won't ever do that again....
