You don't need a crystal ball to realise that he won't be getting out but you do need rose tinted glasses to think he might! 
Stranger things have happened. Though now it's beginning to sound like a mass vendetta even if he is presumed innocent,for it's the power of the public that'll keep him where he is and NOT so much the legal system. Let's face it,it only needs the usual war-cry from the relatives saying that " they all fear for their lives " and that'll be the end of any more thoughts of appealing, that would be my reason for his continued incarceration even if his innocence is proven.
Too many people have too much to lose otherwise !!
