Goodwins anthropological analysis of the professional vision is an effective illustration that individuals of a specific profession develop a perspective of their own, similar to groupthink, which both impairs and improves an individuals perception of an individuals action. Goodwin especially centered on Sgt Duke as an example of an individual who was deep into the professional vision concept, perceiving the cops actions as justifiable, in light of Kings response to the arrest, which he interpreted as a manner of aggressive behavior.
Officer Powell, one of the accused, proved this assumption about professional vision when he justified his actions, where he landed the most blows to King, as reasonable when he will put his perception on the action he did during the arrest. It is striking that Goodwin did not argue for or against the case discussed, but most helpfully, he demonstrated why the officers and Sgt Duke perceived the arrest as an arrest, and the cops physical actions against King as responses to his aggressive behavior. This perspective illustrates and brings to reality the professional vision, a vision developed because of individuals internalization of their interpretation of actions, as considered necessary in their profession.
