I am not doubting the victim or the police, but in the video it does seem that the 2nd BG is in the store during most of the confrontation. Secondly, I thought I saw him come out only when his buddy was in trouble. If that is the case, his sentence might be much lighter. Now if he confessed to robbery, then he is in more trouble.
