I talked to a guy who was on a sex offender registry for "urination in public" at a bar one time. Sounded like a travisty of justice when he explained it that way. Talked to someone else about him afterwards and while yes he was "just peeing in public" he did so in the view of a few young girls who walked past his house on their way to school on multiple occasions and with a erection.
Knew another guy who did a few years in prison for "just a bag of weed", again that was true in a technical sense, he was on parole for a strong arm robbery and had the bag in plain view when he got pulled over.
I'm not saying nobody is ever innocent, but everyone I talk to claims to be and it never holds up.
