Against Nevilles' better judgement,and because of all the guns in that farmhouse,while he was downstairs,and YOU think that Jeremy was upstairs,Neville WOULD have shot Jeremy in his legs to put him out of action.,or cause injury which would have rendered him,Jeremy, guilty of attempted murder.
At this juncture,Jeremy has studied law whilst being in prison,so will know far more than any of us regarding his case and because of his studies,which also includes mental illness/psychology,he will be better read than those of a degree level,and so will be in a more knowledgeable position to put his side of the case together in order to prove his innocence.
Do you,or anyone else think that Jeremy would go to the trouble of studying if he'd been guilty ? Nope !
He'd have topped himself well before now,as he wasn't the type of guy to have faced the rest of his life being locked up. ( that's if he'd been guilty )
This is entirely different because he's fighting for his freedom,and will continue to do so. Innocent !
