@parados,
I never said the cop was acting on Brown's frame of mind, I said Brown was working with his own frame of mind. HE KNEW he had just robbed a store and he knew that there was now a cop asking him to talk to him... You put it together. This wasn't 2 days after the robbery, it was less than 20 minutes later. You tell me what someone's state of mind is after committing a crime and then seeing a cop? It sure isn't a thought of innocence, it more than likely an "oh ****" moment. This had to have had a factor in the way HE dealt with the cop.
You are correct in that the cop didn't know what Brown had just done, but Brown knew. The cop was working with him as he saw him and that was someone walking down the middle of the street. From that point on the encounter is in question.
