I have no idea about any of that. That won’t define anything regarding the actual shooting.
I am more interested in the actual crime scene and what occurred at the time of the shooting.
Here is what I've pieced together, taking into account both the officer's and the witness's statement/interview.
Mike and friends were walking back down the street in the middle of the road. The cop was on his way to a shots fired call. Probably not the first time, either. The boys moved only enough to let the cop go by. He yelled at them to "get the f on the sidewalk. They responded with a poetic and flowery "NO". He hit the brakes and backed up. They stood firm in the street, refusing to budge. The cop tried to open the door, but Big Mike intentionally or unintentionally slammed the door shut. The officer yells "I'm gonna kill you". Big Mike reaches in the window and punches the cop in the face. Big Mike tries to take the gun, or thinks he can keep the cop from pulling the gun. He knows he's in a mess now. In the struggle, the gun fires. Mike backs away from the window. The cop pulls his gun up and fires at Big Mike. Hits him. Mike takes off. The officer jumps out and fires again. Mike is still up. The officer continues to fire as Mike comes to a stop and is sinking to the ground.
All of this happened in about 60 seconds.
