I'm not expecting first degree murder charges, but I do hope for charges like second degree murder, manslaughter, or reckless homicide. I just see first degree murder being too hard to prove.
That being said, if deadly force was justified, unfortunately, Daren Wilson would not have had to stop even if Michael Brown had his hands up(which is a whole new issue). Both sides seem so sure of their side being right, with the main argument being their side would have to be incredibly stupid to be in the wrong/why would they lie? Well the side in the wrong is stupid, and whatever side is in the wrong has reason to lie.
