Stealing one item is not a big deal. Multiple kids stealing multiple things on a frequent basis would likely put the store out of business eventually. So, how DO you deal with widespread theft? Other than shutting down?
I’ve read here that there are many solutions, but haven’t seen any particulars yet.
I think convicted shoplifters 16 and older should get the stocks for a day, convicted burglars should be caned and convicted murderer-thieves hung. Publicly, every Saturday at noon in city squares all around America. The ‘beginners’ get to see what happens should their criminality progress. Old school, I know, but I suspect it would significantly reduce crime.
