A large number of police officers are former military personnel. It's not surprising that this militarized philosophy is common among police today.
Our militarized police like to call the rest of us "civilians" but they run straight to their Union when any superior calls them out, and they hide behind the same lawyers as the rest of us and ask for favors from the prosecutor and court.
We need to keep the teacher unions and break the police unions up, then subject them to higher standards of conduct, and LOWER standards of defense and evidence... We have allowed them to become a wild pack of dogs and they need caged up, put back on the leash, or put down.
