As an African American man who served the city of St. Paul as a police officer (patrol, foot beat, SWAT, detective), I was one of very few officers who policed the city I grew up in and in which I raised my own children.
Based on my 28 years of experience, I would estimate that 95% of preserving public tranquillity is about peacekeeping. Probably less than 5% is about enforcing.
The term "law enforcement" has hijacked the peacekeeping mission over the past century. It emphasizes force and implies suppression and oppression, which I consider a betrayal. I cringe at its every utterance, especially when hearing police officials use the term in opposition to "community policing."
America went to community policing in 1836, based on Sir Robert Peel's nine principles of policing established in London in 1829. Listed below is my oversimplification of Peel's principles. The goals of community policing are:
1) To prevent crime and disorder as an alternative to suppression by military force.
2) To depend on public approval and to maintain public respect.
3) To achieve police objectives by means of public cooperation.
4) To earn public trust and cooperation, which declines proportionately with the use of force.
