I have watched several interviews with Dorian Johnson (Mike Brown's friend) on his story of the events leading up to the shooting. Not sure if this has been discussed, sorry if it has.
DJ says the officer (Darren Wilson) drove up beside the two who were walking in the street and told them to "get the eff on the sidewalk". DJ said he explained they were nearly to their destination, the officer kept driving. Dorian said the officer then backed up to the two of them one or 2 seconds later (they were still on the street) and couldn't exit his police car because the boys were positioned so close to the door ("it ricocheted off us" when he tried to open the car door), DJ speculated maybe that made the officer upset. DJ says Officer Wilson then grabbed MB's neck with his left hand, through the open window, while still seated in the car and tried to choke MB while MB tried to back away but couldn't.
DJ said that's when MB was first shot. The officer pointed the gun at them with his right hand while still holding and pulling/ tugging Mike Brown through the window. (Other witnesses describe a scuffle- officer in car, MB outside driver window as well but couldn't see what was happening inside the car). The gun went off, the boys were stunned, MB had blood on his arm and they took off running. The rest is on video, here's one link

Any thoughts on this part of the story? It's hard for me to imagine MB not being able to break a one-armed grip while standing, but that's jmo.
