"Officer Wilson … was the victim of the assault we were investigating."
Once it had been established that the living, armed individual was the "victim" and the dead, bullet-ridden body had belonged to the "assailant," continued the detective in his September 3 grand jury testimony, "One of the sergeants with Ferguson [gave] me a brief walk-through to start my investigation so I [could] have a logical starting point from where I would start my video, photographs, and looking for evidence."
That unnamed sergeant, most likely, was the supervisor who had told Darren Wilson to leave the scene after the shooter told him that Brown had tried to take his gun.
From its inception, the shooting of Michael Brown was not investigated as a potential criminal homicide, and the inquiry was an exercise in validating the killer's story, rather than testing it against the available evidence. The assumption was that killing was part of his job description – or, as Wilson has subsequently told George Stephanopoulos, "I did what I was paid to do."
If Wilson had been a member of the productive class, rather than a state employee licensed to dispense aggressive violence, he would have been presumed legally innocent, but required to justify his actions. Because of his occupation, however, Wilson was considered both legally innocent and presumptively correct, and the investigation became an exercise in justifying the shooter's actions, rather than an inquiry into their propriety.
