Realistically, neighbors are going to hassle people more about this than cops. No cop wants to deal with any more of this than they're forced to.

Petty crime will also decrease massively, freeing up police.

Not to be overly cynical, but I don't think petty crime gets much attention from the police, at least in SF.

I would say in most major cities on the west coast it doesn't get much attention at all. Theft as a crime is generally something the police will never get involved in - this is why you should always have insurance for valuables.

When I had my car stolen in Seattle - it was still given parking tickets after being reported stolen a few days prior. I had to visit the city council in person to get them written off. On top of that, the only reason it was only found was because the thieves made a bunch of noise when getting out of the car and abandoning it. So, a lady reported the car to the police for it being a nuisance. Cranky people - sometimes good for something...
