Other kinds of property crime? The costs of enforcement are high compared to the losses caused by individual cases, prioritization is understandably a difficult problem to solve.
The pervasive problems you see in places like SF or much of the UK are just far more boring.
Also say that you're thinking of intervening personally.
That usually gets them going.
In a similar vain I was the first on the scene of a car crash in the UK, where the driver had exited the vehicle through the window (no seat belt) and was bleeding in the road. When the police turned up they casually and slowly walked up the road towards the scene.
It made me wonder if there was a good reason for this, like to control adrenaline, make better decisions, have time to assess the situation. Or if they were just jaded from seeing it a lot.
That said, the policy can be, and certainly is, applied in imbalanced ways when justice is pursued over pragmatism.
