If cops followed the rules and laws to the letter, then you might have something here, but they aren’t “law enforcement” as much as they are “bad guy removal”.

They decide who’s a bad guy, and eliminate them. When little Johnny football star and his friends get caught smoking a little weed, they get a warning to straighten up and sent on their way because they aren’t bad guys. But a “gang” of poor kids toking up are on a dangerous path and need severe intervention to keep them from becoming bad guys.

They decide who needs to be executed without due process, or proof of guilt. They decide that the off duty officer who can’t form a coherent sentence should drive home. They decide which high profile members of the community get a “heads up call” before the search warrant arrives.

The people who make the laws can’t be blamed because all of the shittiest things that make cops bastards, aren’t part of the laws at all.
