OJ and Blake were jury nullification. With OJ it was racial and with Blake everyone hated the woman.
Anthony was lucky enough to have a brain dead jury who were so stupid they only considered 1st degree murder although there were several lesser charges as well as the fact that opening/closing statements are not evidence but they deliberated them as if they were. Additionally they admitted they assumed the huge public presence was pro Anthony and that swayed them.
I have no doubt Arias will be found guilty. My guess is death. We'll see soon how brilliant I am, or not
