Part of the reason there is not a lot to do is because they focus on traffic tickets and teenage parties. A thug is a lot less likely to drive around a subdivision looking for a car to break into when he/she knows the odds are high they are going to get pulled over for a broken tail light.

Fixing Broken Windows. NYC, in an effort to cut down on crime, started to enforce subway fairs. They would randomly ask to see proof of fair. Of course, the average Joe or Jane were able to show this. The people who were not able to also had very high odds of having something else on their record. I guess you can fix broken windows but you can not fix stupid.
I have always found that people who have anything bad to say about cops, either in the city or burbs, have usually had an interaction with the police that did not go their way.
From the parent who is oblivious to just how much of a tool their child is, the soccer mom who just does not understand that driving an SUV does not give the right to drive like an a-hole to the guy who gets pulled over and drops the name of a second cousins friend who is on the force in Rochester and does not understand why that was not good enough to get out of a speeding ticket and the lawyer who thinks they can speed in the school zone and should get a "professional courtesy" when they get pulled over as well.
It is pretty easy to spot the a-holes above in any setting.
