"I don’t like to see this happen, but, is it really a good use of law enforcement resources, to check into bathroom graffiti or defacing a picture in a subway?"

No. If police investigated every instance of offensive graffiti, they wouldn't have time for anything else.

Good point. Heck, when you look at how much graffiti there is in some places, police would do nothing else but try to catch graffiti “artists”. Priorities need to be set with law enforcement resources.
