"Wilson's friend" is not an accurate source of Wilson's story. He needs to tell it, or the Ferguson PD needs to tell it. If we're not going to believe anything that comes from Brown's friends or associates, we should, in fairness, discount anything that comes from "Wilson's friend."
A police car arriving on scene two minutes after someone is shot is not back-up.
There is no dashcam video of anything that happened because the Ferguson PD doesn't have dashcams in any of its cars. Must not have had any money after spending it on upkeep to that $300,000 MWRAP.
You won't believe Wilson's story unless you see him tell it? Then you can't believe Brown's story unless you see him tell it, and so you can never know anything.
Brown's "associate" who told their side of the story has a criminal record, he knew he committed a crime just minutes before the shooting, and he had some pretty outrageous claims - the cop grabbed Brown's neck from his seat in the car? Brown was shot in the back? - so it's pretty hard to believe anything he said at all. The only one we're sure saw the incident, and had no reason to make up a story, is the one who described Brown as going after Wilson and not stopping even after shots were fired (that he thought hit Brown).
Back-up cannot arrive in the middle of a fight. Remember, when seconds count, the police are only minutes away.
It is too bad that Ferguson didn't have dash cams. I think there are too many police dep'ts that haven't put the appropriate priority on those. Some of those dep'ts are in quiet and safe areas where they don't expect to need them, but all it takes is one unfortunate incident to find out that all police dep'ts need them now.
I can understand why you might have a dim view of police dep'ts, esp. if you live in a place where their performance hasn't been so great. There have been some pretty ugly incidents recently, too. But I've met some very good cops, and have had friends who were good cops. So I'm inclined to want to know more about a situation before I decide the cops were the bad guys. Particularly if the situation involves a white cop, a black guy, and Al Sharpton.
