A lot of guys want to become cops so they can shoot bad guys. Big cities have batteries of psychological tests which filter out the applicants with what we could call wrong impulses. Unfortunately, it's tough to find cops in small towns, particularly in Alaska. So prospective cops who are rejected by big city departments are hired in the small towns. The smaller and more remote the town the more likely you are to encounter a cop who is nuts. There probably is no solution to this problem.
