If I were him,I think I'd want a GPS satellite tracker so that there's no argument as to where he was at any given time in case there should be a crime and he gets blamed again !!
To be institutionalised for so long will be the biggest hurdle to overcome and to resolve this he'll need the genuine support of friends as well as professionals.
Jeremy's no fool and will have been keeping up to speed with the news so will have realised how things have changed over the years.
I think he's got a level head on his shoulders.
Compensation I'm not sure of,but he'll make a packet in interviews and the like. I doubt that his mind has turned to compensation-------more about his freedom and to prove that he's no killer.
Again,whether he'd have anything to do with WHF remains to be seen,though again,unless he was pressured in any way,I don't think he'd bother.
There could be restrictions about where he lives,I don't know,but I'd keep away from Essex if I were him.
