You needn't wonder about it. You're right. Revenue enhancement activities like parking and moving violations are a higher priority than recovery of stolen property.
The actual priorities of local law enforcement shake out something like this in most places:
- Homicide
- Sex crimes other than domestic abuse of adults
- Bank robbery
- Revenue enhancement (i.e. traffic tickets)
- Felony assault other than domestic abuse
- Domestic abuse
- Other property crime (vandalism, burglary, car theft)
It's probably not a coincidence that priority is inversely proportional to the number of incidents of each type reported (with the exception of ticketed infractions). I realize it's cynical to call traffic enforcement "revenue enhancement" because enforcement of traffic and parking regulations has value to society beyond the way they subsidize other municipal budget items - but it's also silly to dismiss that revenue as irrelevant to the relative priority placed on those activities.
