Here is what I am willing to wager on will happen: The local coroner will say that Brown was NOT shot in the back. Only exit wounds coming out the back.
The family's famous M.E. Baden will say that "it's possible the wounds on the back are entry wounds" as he is being paid by the family. Even if there are NO entry wounds on Mike Mike's back he will twist the words in such a way the family attorneys can continue to say it's not conclusive.
I will die in my sleep the night the family's hired M.E. says "It looks like Mike Mike was NOT shot in the back. Everything appears to be consistent with the cops story."
