Specifically, the job of the police officer involves giving orders to strangers and locking them up in cages if they choose not to obey. Unless the police officer is a complete sociopath, he would never consider acting in such a way in his private life. With his blue polyester in the closet, for example, the off-duty police officer would never consider putting his grandpa in a cage if he refuses to obey orders. He would never consider electrocuting his children or his grandmother for refusing to do what he tells them. He would never consider beating up his neighbor if she refused to stop her car and show a picture of herself embossed on government plastic. But he is expected to do precisely these types of things to people he doesn’t even know in his “professional” life if they refuse to do what he and his bosses tell them.
The fact that many, many police officers are indeed complete psychopaths should thus not come as a particular surprise. Indeed, the job is tailor made for the psychopath and the sociopath who is comfortable with feelings of cognitive dissonance. People with normally calibrated moral compasses would shudder to think that they would be required to lock people up in cages, electrocute them, or beat them with clubs for not doing as they are told. It would confuse and trouble the normal person to think that by putting on a blue polyester suit, mustache, and riding boots it was suddenly morally acceptable to order people around at the point of a gun (not to mention the icy shudder they would feel at the thought of wearing the ridiculous kit itself). It would horrify the normal person to think that part of his job involved smashing down strange people’s doors, taking their children, shackling them, locking them in cages, stealing their drugs and guns, and shooting them if they happen to resist.
The man with a normally calibrated moral compass is equally disturbed to contemplate that the purported justification for acting in these barbaric ways was that politicians, of all people, told them to. It is not as though God Himself or the Pope gives the police officer sanction to lock people in cages and to order them about. Quite the reverse, the sanction comes from people of such sterling moral character as the coke-snorting drunk driver, Bush II, and the drug-cartel-connected perjurer, Clinton I. The sociopath and the psychopath are not troubled by the fact that their only justification for ordering strange people around is that a pack of corrupt millionaires in Washington or Denver told them to, which is what makes such people sociopaths and psychopaths in the first place. The normal person, in contrast, is not willing to do things to other people that they clearly resent or despise, or to order them to do things they oppose, just because a politician says so.
