I guess the thought that if Wilson simply wanted to shoot Brown for no reason other than that Brown was black, he could have just cruised up to Brown, opened his window, and pumped a bunch of bullets into Brown without having to pull Brown into his car to shoot him never occurred to the Brown mourners.
Maybe that's a new police technique I never heard of. Roll down the window and pull the suspect into your car without getting out of the car to handcuff the suspect. I guess it must be a lot easier to pull a huge suspect like Brown through the window and have him be able to grab for your gun. (snicker)
Gonna have to try that! That is when I am not driving around looking for dogs to shoot.
