Do you genuinely believe that anybody would receive a fair trial in Belize?
I'm coming from a country significantly closer to the developed world than Belize, and yet people generally don't have fair trials here. I can't imagine how much worse it is in Belize.
This is hyperbole. There's nothing to suggest that he would not receive a fair trial other than the paranoid ramblings from McAfee himself.
He quite possibly killed his neighbour. Why shouldn't the authorities get hold of this guy?
