#88. A Minor Crime Spree
Michigan used to have a law forbidding minors from pleading guilty to a crime without a lawyer. I found this out by accident when I was 13, and used it three more times before I was an adult. What happens is that I, as a minor, would just plead guilty, they would then give me a sentencing date and let me leave. Then a week or so later I would get a letter stating that it is not legal for me to plead guilty without a lawyer and that my case was dismissed or thrown out because of it. I got out of three minor possession tickets that way.
