The Oklahoma City police force redrew its patrol boundaries. The result: more cops near you. This will supposedly reduce the response time when 911 is called, which is a good thing. You can read about it in the link below.
An issue important to DUI arrests is the whether the arresting agency has jurisdiction in the place where a stop and arrest took place. In the metro where one city flows into the other, officer's often lose track of the boundary or simply fabricate the location of an infraction. At times, I've found an arrest to be unlawful for reasons related to this subject.

DUI attorney Alan R. Woodland is skilled in finding these issues.
