The problem is, from what I've seen, that although there are many good, decent people who just want to serve and do the job in positions like CO or policing, there are many that are attracted to them for the wrong reason. They one that are there for the wrong reason are usually powerless, ineffectual types in their own lives (or feel that way) and seek out these types of positions because it gives them what they're craving, that sense of power.
