We don't yet know what kind of car the cop had. Some call it a truck so maybe SUV?
Most reports are it was a car, one did say truck.
My Ford truck has a full frame around the window. It's conceivable that Brown might have slammed the door on the officer's head instead of leg. That would explain the grappling, the "let go or I'll shoot, I'm going to shoot", the initial shot (at least), the shooting of a fleeing felon.
You be squashing my head in a car door, darn right I will hit back with whatever hammer I have.
I've been trying to figure out the details of this myself. The swollen head may well have been the door being slammed back, it could also have come from the struggle. Dorian Johnson had the door being slammed back (as a rebound) and then the officer reaching through the window, obviously of course Mr. Johnson's credibility is in question, I wonder though if he might have had this part right? Or at least partially right in that it started through the window, perhaps by Brown reaching in?
But where did the report of the officer giving warning come from? Do witness stories differ on that?
That's from Dorian Johnson's account, the anonymous one never claimed to witness that part and I don't recall the woman mentioning that. However Johnson said it was that the officer let go after first grabbing his neck and then his shirt and then said he'd shoot.
Incidentally,
here's something I just found: Dorian Johnson told police and FBI about the cigarillos. Recall that he wasn't interviewed by police initially, it was a couple days after his media interview that he officially talked with police:
“We see that there’s tape, that they claim they got a tape that shows there was some sort of strong-armed robbery,” said Freeman Bosley, Johnson’s attorney. “We need to see that tape, my client did tell us and told the FBI that they went into the store. He told FBI that [Brown] did take cigarillos. He told that to the DOJ and the St. Louis County Police.”
This article also (seems to) indicate the officer was not aware Brown and Johnson were involved in the strong-armed robbery. It also confirms that Darren Wilson is white.
