Joking apart,and on a more serious note, what JM did puts her in the same category as Maxine Carr,except that Carr hadn't" known" beforehand that her boyfriend was going to commit murder. Carr was then imprisoned for perverting the course of justice for giving a false alibi,which JM tried to do when blaming MM. JM was either trying to " shield " Jeremy,or she'd still felt something for him and knew in her mind that he couldn't do such a thing.
JM's credibility would have suffered tremendously to those who read forums,etc such as this one,and she has to live with that.
Will JM ever admit one way or the other ? Truthfully ?
It'll take a person of great strength to admit to their mistakes. In fact,at this late stage,it would be far easier,and certainly would have been before now,to tell the world " he's guilty "than to admit that he's where he is because of her. It would have shut everyone up. So why doesn't she ? JM's the only one that'll know,besides himself, if he committed the crime or not,having professed to have known him well.
Her family will be of an age to now know what goes on and doubtless will have the internet. There'd have been questions asked,school pupils to contend with,etc etc,the case goes beyond the fact that it happened all those years ago and because of uncertainties which have arisen,it'll never go away.
