There are a number of witnesses who say that brown was surrendering, however no video of this has turned up despite the likely-hood that a fight with a police officer would almost certainly be recorded by someone who would witness such a fight.
I agree with your first points, but this one... the fact that there's no video says nothing about the circumstances. If any conclusion were to be drawn from it, I would conclude that the only thing that means is there is no video. If someone had it, they would have sold it to a media organization for a pretty penny already.
That's just not a credible concern.
reminds me of another one I saw.
