Why is it considered a felony rather than simple theft or shoplifting?
When my job gives me a task that's hard and complicated and has lots of paperwork, I don't get to say "naw I don't want to".
The complaint is exactly that they "don't prioritize investigating it", because that is the point where police are actually providing a useful service.
I would probably see it more like low priority bugs in an issue tracker. They only get done when there's nothing with higher priority or someone takes a person personal interest.
The police will do nothing, because our governments are responsive to nothing because they don't have to be. Safe seats and gerrymandering have rotted out Democracy.
