It is extremely difficult to reform an organization with a publicly paid for union, a lot of guns, the power to kill and get away with it, and a intelligence branch, combined with the ability and intent to intimidate the public and the politicians who may want change-
Cops in CA were going to folk's houses who were trying to restrain the obscenely generous retirement benefits for the public unions, in order to intimidate them.
If the militarization of the cops continues much longer, and the intelligence/surveillance continues, the cops, Federal ,State and Local, will BE the government. THEY will be telling our "representatives", how high to jump.
