Your position is (IMO) contradictory because, despite your opinion that Luke is guilty, you also do not believe that his guilt been established "beyond all reasonable doubt". Therefore as there IS doubt about his guilt (certainly as far as the jury was concerned), he should surely, at the very least, be entitled to a re-trial in your view? If not, why not? Just because you think he's guilty?
I understand what you are saying but he has had several opportunities to demonstrate innocence and failed every time. The last review wasn't even referred to the court of appeal.
I don't believe the trial proved that he was guilty beyond a reasonable doubt simply because the evidence was exclusively circumstantial. I can understand why the jury was conflicted but ultimately decided on a guilty verdict.
Sandra Lean is calling for an 'independent review' of the case but that is something that can only be done if compelling new evidence is found or a new witness steps forward with credible information. None of that has happened. There have been no similar assaults of young woman in the Lothians so one can only come to the conclusion that this was an isolated event and that the killer is behind bars.
