Police officers are vocational sociopaths.
A sociopath, as the term was defined upon its introduction in 1930, is someone who displays a “disposition to violate social norms of behavior” through “deceitfulness … impulsivity … irritability and aggressiveness … [a] reckless disregard for safety of self or others,” and a “lack of remorse, as indicated by being indifferent to or rationalizing having hurt, mistreated, or stolen from another.”
Law enforcers – as opposed to peace officers, especially private security operatives – have official permission to employ aggressive violence and escalate it to lethal levels if they meet resistance. They are clothed in “qualified immunity” that protects them from accountability and liability for committing acts that would otherwise result in prosecution. As noted above, when they kill someone, police officers are immediately designated the victim, and the decedent is assumed to be the perpetrator.
