It this witness’s story is correct it was the officer that escalated the situation from the get go.

“...The two walked and talked. That’s when Johnson says they saw the police car rolling up to them.
The officer demanded that the two “get the f—k on the sidewalk,” Johnson says. “His exact words were get the f—k on the sidewalk.”
After telling the officer that they were almost at their destination, Johnson’s house, the two continued walking. But as they did, Johnson says the officer slammed his brakes and threw his truck in reverse, nearly hitting them....”
But at the same time he is talking to media and has a lawyer, a good recipe for a bad witness. Ferguson does not have dash cams or recording devices which is appalling!
However, we do have a thing called an autopsy. The autopsy can collaborate if the victim was choked and if his hands where in the air when he was shot.
We also have forensics to determine if a shot was fired inside the police vehicle.
