Also named in the police report is Dorian Johnson, said to have been Brown's accomplice in the robbery. Johnson is also a witness to Brown's shooting and his account of events has been one of the primary pieces of evidence for police misconduct. In Johnson's version of events, needless to say, he and Brown were not perpetrators of a crime.
All of which gives rise to a mystery — why haven't the police arrested Dorian Johnson?
Regardless of whether the use of deadly force was justified as a means of apprehending a robbery suspect, on the police's account of events one of the suspects — Johnson — was very much not dead. Why not arrest him? He isn't missing. He's been doing interviews with TV stations.
