It is my opinion... There isn't a shred of evidence which supports Marks claim of innocence
The fact that you continue to deny the obvious really speaks to your own shortcomings, not Mark's, and not Mark's family. Your stubborness is quite revealing, and demonstrates the problem inherent in all miscarriage of justice cases, that people who form an entrenched opinion on a case always dig their heels in when challenged, no matter what subsequently comes to light. I can't think of many exonerations where the original police and prosecution admit they were wrong. The Daniel Morgan enquiry exemplifies this phenonmenon.
There are plenty of reasons in this case to doubt the safety of the conviction, the fairness of the trial, or the thoroughness and impartiality of the police investigation - a quick browse of our website gives most people pause for thought.
However, even if there were no new evidence at all, this would reveal nothing about Mark's guilt or innocence. Many innocent people languish in prison because they are unable to find fresh evidence. That doesn't make them guilty. The Westminster Commission on Miscarriages of Justice recognised this problem in their recent report, 'In the Interests of Justice', calling for changes to the way the Court of Appeal assesses wrongful convictions so that they can be overturned even where no fresh evidence exists, but where there is nevertheless serious doubt about the verdict.
