In the thread, they describe how the company waited until they had recorded multiple instances of theft by the suspect until the total amount of stolen goods had exceeded the threshold for a felony.
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.
