IMHO, George Zimmerman's actions were reckless, and a case can be made for manslaughter, but it is a huge leap in logic to conclude that he committed murder. He provoked Martin, was getting his ass kicked, and in the heat of getting his ass kicked, shot Martin to death. This is not murder, folks. However, this is what Zimmerman has been charged with, and it looks like there will be no option for a jury consider manslaughter. To be honest, if I were on that jury, and the only options available were either acquittal or guilty of murder, I would be leaning strongly towards acquittal, because the prosecution is going way too far in it's attempts to send Zimmerman to prison. Is this out of political expediency because of all the publicity this case has garnered? Who knows, but that is not germane to my logic. Manslaughter? OK, I can consider that. Murder? No way.
My prediction, based on the above analysis? Zimmerman walks.
