Fortunately there's plenty of world outside of the United States, where peeing outside does not make you a sex offender.

Public exposure convictions/registration from people who are innocently peeing somewhere they shouldn't is vanishingly rare. As in, I've never seen a report of a conviction that I found credible, but if I did, I'd bet lots of money that you couldn't find a second one. What I HAVE found is lots of people on the registry for indecent exposure who tell their friends "I was just peeing in alley, I swear", but I do not count those as credible.

Do you really expose to the public when you are turning your back to everyone?
