what is the requirement for manslaughter in a nutshell?
Ill will, spite or hatred.
HIS HEAD WAS BEING SMASHED ONTO THE CONCRETE!!!!!!
Culpable negligence. Truly, they can't get to manslaughter without twisting the facts of the case.
It is the reason why the prosecution pushed hard on emotional appeal to the 6 women jury. They, the prosecution, only hope was to play for illogical emotions and not on the facts or the rule of law.
It could be because that most of the women understand the rule of law and are looking for an authority figure to help clear up some jury member(s) who is/are confused.
