> if police know their local prosecutor wont prosecute certain crimes (theft, property damage, drunk and disorderly), police tend to stop trying to arrest people for those crimes, and the overall rate for those crimes will go down (in the data at least). This is why you have to use something like victimization surveys, which appears to be what their data source has done.
