Cops in my area did a sting operation to find out who was putting trash into one of the municipality's wealthy benefactor's trash bins at night. They also did a six month investigation to catch some high school kid who spray painted "BLM" on a street, but completely ignored whoever wrote "WLM 2" next to it the next day.

The police know who they work for, and they will expend all the resources they have to go after people they simply just don't like, no matter how petty the crime.
