Personally, "effectiveness of police" isn't a make-or-break criterion for me for where to live. I agree that petty property crime is out of control in this city, but I never feel physically unsafe. And regarding property crime itself, my car is garaged, and when it's out and about I never leave anything in it visible from the windows. As for my home, I live on the 4th floor and have two big heavy doors, one with a deadbolt, between me and the street. Home break-ins are pretty rare in my neighborhood anyway, but even if someone did want to break into a home around here, my home is not the low-hanging fruit that a burglar would zero in on first.
