At this point I think its this:
.01% no charges are brought against him, because reasons
95% he is scapegoated and left out to dry, with what the witnesses are saying, and if the autopsy shows bullet wounds in the back and front of Brown at closes proximity, he will be made an example of to "appease the masses"
4.99 % he is charged, but the evidence is tainted somehow.
Wow @ the head of the prosecutors office, some people have no awareness of PR and how it works do they?
Or he doesn't care and with the arrogance being shown by the entire local establishment it wouldn't surprise me.
