In the news conference, Dr Boden said the "distance" could have been ONE FOOT or thirty feet.
About the officer;
I read the link......in bold print at the very top it says that officer Wilson didn't know about the robbery or the description of the suspect but then at bottom it says the police put out a description at 11:52 and Brown was shot at 12:01.
Then in the pictures below there it shows a red cap near the door of officer Wilson's vehicle which to me coincides with the statement of a fight or scuffle at or near the police vehicle and a ways from the body of Brown which is consistent with the officer giving chase and the victim turning on him.
Wonder if Brown had a football scholarship, his smug/thug behavior and "I can do anything I want" attitude is like a lot of those always in trouble players.
