Regulation enforcers have to stay busy to do their job and to reduce their visibility they often avoid wearing uniforms. Since there are far more regulations than people are willing to obey there is always more work to do. Instead of waiting for some problem to occur they use expensive equipment and careful planning to seek out violators. When violators hide they request bigger budgets to ferret them out. To keep their identities secret regulation enforcers rarely form strong bonds in their communities.
Few people join the police in order to become regulation enforcers.
In recent times there has been a change in the role of the police from peace keeper to regulation enforcer. This change is due to excessive regulation. The libertarians favor massive deregulation so the police can go back to being the peace keepers we respect and admire instead of the regulation enforcers we despise and avoid.
