As has already been mentioned to some extent. In my neck of the woods, budget cuts have caused the police force to lay off so many officers that they don't even respond to crimes anymore unless they are serious. They even admitted this in public statements to news agencies in efforts to garner public support for more funds. They don't even respond to minor assaults (unless one of the involved parties is the one calling), car break ins, simple theft, vandalism etc... 911 has so few employees that it's often busy when you call.
As far as more serious crimes, they do respond but since they also don't have the investigation resources...rapes are written up as assaults unless they are heinous. Strong armed robbery as theft or criminal mischief.
Stats say we're down across the board, except for murder of coarse because you can't call that anything other than what it is. We've had more of those already this year than in the past 25 years and there are 3 months left to go.
