Sounds just like Labour’s laughable crime statistics in the UK: if they aren’t arrested, tried, and/or convicted then crime magically decreases!
One mall in Ohio enacted a curfew, age restriction, etc. as a last resort. The usual voices cried foul but it worked.
The Mall of America did that as well. Anyone under aged 16 needs an adult with them. Crime went down massively. They had some real problems for a while even after having an an actual police precinct at the mall itself as a deterrent.
