It really depends on how granular the laws get in certain areas.

But for example indecent exposure may not be a mandatory register on the sex offenders registry, but within 200m of a school or playground is mandatory. (even if it was 2am on a sunday in the middle of the school holidays during the dead of winter.) Like the whole getting booked for drunk driving for being drunk and going to your car to get a jacket.

There are people who are on the register who shouldnt be and people who absolutely should be who arent.
