‘I believe the police attitude was “Not such a big deal. It’s just kids.”’
A form of Entrapment. Let the kids do it and get comfortable with it and in the habit of doing it. Then when they turn into adults come down on them like an anvil dropped from the top of a ten story building.
If this law passes constitutional muster, then would they kids have to be banned from wearing tight and skimpy clothing? Of course not. They’d basically become the modern-day Hitler Youth.
