Where did it say he got jail time? And this isn't vigilantism. He was stopping a crime while it was being committed, not administering justice after the fact. I would be surprised if this makes it to court. He was acting to save the other young man, who was clearly being beaten. He acted using a reasonable amount of force, actually less than what a peace officer would have used (personally I would have loved to watch that bully writhe in pain with 20,000 volts from a cops taser). Please link us the rest of the article, I would like to know more.
