There seems to be some disagreement (surprise!) about how or why this happened.
Brown supposedly stopped at the QuickTrip (but may have been another convenience store) that was looted and burned down and stole something. The store employees called 9-1-1 about it. While he was walking home the cop stopped him not for stealing, but walking in the road. The cop told him and his buddy to walk on the sidewalk. Brown mouthed off to the cop and that was the trigger for the cop to stop and give them the once over.
When the cop tried to get out of his car Brown pushed him back in his seat and then jumped him. Brown went for the cop’s gun, one shot being fired, but missed. The cop got his gun back, pushed Brown back (who suddenly raised up his hands in surrender) and shot him once. Then the cop got out of his car and shot him three or four more times. Brown fell down to the ground and the cop shot him a few more times.
Unfortunately, the cop did not have a dash cam or any other recording devices that would help determine the facts.
There were several witnesses to this and they all say that the cop murdered Brown.
If I am wrong about what I have just stated in the above be sure to correct me.
Lending some weight to the story as reported to you was the appearance of a "Community Activist" on a news show who seemed quite reasonable and very subdued for that sort of fellow. His only remarks in the vein of, "We are waiting for further police reports."
