Sounds like you have no experience let aloan any knowledge of law enforcement.
There are two forms of LE. Proactive law enforcement, the kind the left hates. Where law enforcement officers are peace officer. They keep the peace. Their objective is preventing crime and keeping the peace. To do that profiling is a must. Jacking up known criminals letting them know who's town it is. Keeping a high profile to deter criminal activity.
Reactive LE is known as progressive law enforcement because it's political, usually the Chief of Police of these agencies are appointed by liberal/progressive city councils. They react to crime after it has already happened. They usually refuse to uphold the oath of office they took to uphold and defend the Constitution of the United States. They refuse to enforce federal laws. They forbid their officers to profile or to jack up known felons. They don't keep the peace so they aren't peace officer. They are more in line as socialist gestapo.
Many if not a majority of these political liberal/progressive police chiefs belong to the"Police Executive Research Forum" (PERF) aka "National Organization of Progressive Police Executives"
What the MSM Didn't Tell You About Holder and the Police Chiefs
If you live in a high crime neighborhood, it's very likely your police department practices progressive/reactive law enforcement and the Chief probably belongs to the PERF.
Their membership is kept below the surface but meet with Attorney General Eric Holder on a regular bases.
