Steve,,books like this wouldn't be written if there wasn't any truth in what was said. Because there is every chance that Jeremy is innocent,it's the authors' way of literally telling the world that he's been dealt an unfair deal,i.e. unfair trial and an overall weak defence during the trial and subsequent appeals.
Part of the reason for this,is material hidden from view for years,,,,,,impaired/contaminated forensic tests,,,,
and a " rush " to get him convicted,for reasons that will be made clear in time.
Notice that there were no books supporting Peter Sutcliffe and his ilk,,because it was a foregone conclusion that he was guilty,and those like him were.
It has now been made aware,that along with other MOJ's,,that Jeremys' case indeed is cause for alarm concerning a miscarriage,hence this is why he is determined to see it through this time round.
Why shouldn't the public know that the biggest mistake in history has been made.? It's only by writing books such as Scott Lomax has written,that Jeremy and others like him have got a chance of fighting their corners.
