I used to have that fear. The teachers in my school would tell me that I was going to end up in prison. Some even told me I would end up being some guy's wife. Scared straight I guess. But all I did in school was throw some snowball and skip some study halls to play chess in the computer room.
I never did end up in prison - just a psych hospital. Now I still worry about being railroaded in a psych hospital again. It's much easier to have that happen than a bogus murder conviction.
