<human>: What is the best vigilante story you know of? I'm interested in hearing your stories where the law was taken into someone's own hands and some form of "justice" was dealt outside the law system. Remember to exercise caution with names and specifics.

To kick these off I'll share a personal story: 
Back in 1970-something my friend's mother had a problem when walking home from junior high. A creepy man started following her, day after day, driving slowly beside her and propositioning her as she would walk home from school. She was about 12-13. This guy was in his 30's and was escalating sexual propositions.

After the third day this happened her family called the police. The police looked into the situation but for whatever reason felt there wasn't enough information to formally press any charges. One of the cops came to their house to explain the situation, and then took the girl's father aside and unofficially gave him the pervert's address because he believed the story was true but couldn't follow through with anything legally.

The aftermath was that the father went over and paid the  man a visit with a tire iron. Only the father and the pervert know what happened that night, but the girl (now an older woman) claims that the this guy's car sat out on blocks (say mid oil-change or tune-up) for almost a year without being touched. The grass grew up around it and the house was obviously deserted for many, many months. Either the guy left town fearing for his life or... well, who knows.

Can you give me a shortened version of the text?
<bot>: Pervert harassed 12 year old girl, father likely beat pervert into near-coma (or worse) with tire iron, girl lived happily ever after.
