I can tell you from my personal experience that some of the rural law enforcement agencies will not pursue criminal charges where others would, given the local needs and experiences.

One of my experiences deals with a previously convicted felon in possession of a firearm (two actually) and the local rural sheriff wasn't interested in pursuing the charge due to a number of reasons. The charges were filed by a different agency and is still being mulled over by the local DA for the last 6 weeks as we speak.

This type of situation and charge would not have an eye batted at it by agencies and DA's in the metro areas and this felon would be on his way back to prison for the parole violation and new conviction.
