In the bod old days, we used to joke about there being three classes of people: cops, @ssholes and dummies. the point is that cops see things as clearly demarked by status. The people they normally deal with are the less desireable members of our society. These are people you rarely encounter. Thre are various derogatory terms for them use by lots of people who are not in the law enforcement business. Dummies are those people who, through their inattention to their surroundings or situation, interface (usually negatively) with the @ssholes. The cops, well, that's the other class.
In the present time, we prefer to refer to folks as "wolves, sheepdogs and sheep'. Same interactions-wolves prey on sheep, sheepdogs have sharp teeth and claws and look to some like wolves, but they protect the sheep from the wolves. Sheep who stray into wolf territory get preyed upon and sheepdogs rush to the rescue, although oftentimes too late. Sheep get mad at sheepdogs because they remind them of wolves.
