A close friend of mine was dating a guy who got busted for selling cocaine. Worst part is, he got busted right in her driveway and she somehow didn't even know he was selling it before that point.
A teacher in my HS made up a story about someone stalking her, and even called the cops about it. They came to watch her house for her, and she called to say that there was someone outside her window one night, and it happened to be a night they were watching her house. They realised she had just made it up, and arrested her.
My 12th grade US History teacher ended up getting divorced because he had sex with a student, but the school kindof tried to keep it a secret. Didn't work very well, but he didn't even lose his job or anything. Now this year, he did it again, and was arrested.
