Yeah, I recommend the same thing. Get it on videotape and take it to the police. Don't worry about being a "rat." I don't know where that nonsense came from, that we shouldn't "snitch" or "rat" someone out who's doing wrong. Whistleblowers in companies are often treated like crap because they did the right thing and called out someone doing something wrong. That's the kind of person who should be considered a hero.
