I find your conspiracy speculations extremely worrying Leonora. Simon Hall had no contact with the students or the Bristol based Innocence Project after his prison confession. Fact is he did confess and he did commit suicide alone in his cell after several previous failed attempts so let's not stir up any more silliness.
The same applies to your claim suggesting Joanna Yeates was not killed in her flat. Vincent Tabak tells a different story and unless you have very strong evidence to the contrary I suggest you stop posting personal opinion as fact.
I didn't anticipate that my mentioning Simon Hall merely in passing would stir up such a hornet's nest.
We have already discussed at some length the reasons why Joanna was probably not killed in her flat. If she had been, then the killer's DNA and her blood would have been deposited in her flat. If VT's DNA had been found in her flat, then it is inconceivable that the jury would not have been told about it, by an expert witness under oath. If, as you firmly believe, VT was the actual killer, then he must have killed her somewhere else. In that case, we really know nothing at all about the actual course of events.
Not only did the first persons to enter the flat fail to notice any blood stains, but nor was the jury told about any bloodstains revealed by more thorough forensic examination of the flat. Yet the pathologist's testimony makes it clear that Joanna did bleed quite profusely, mainly from her nose, before she died. Of course her killer might have cleaned up the bloodstains in the flat sufficiently to deceive her parents and the first police officers on the scene temporarily. Once again, if any bloodstains had been detected in the flat, then we may be sure that the jury would have been told about them.
I have therefore very solid grounds indeed for asserting that she was not killed in her flat. You do not seem to be very fastidious about distinguishing between "opinions" and reasoned inferences based objectively on accepted facts.
You write, "Vincent Tabak tells a different story". Of course he does - and obviously that is just what it is: a story. If he is the criminal that you and most other people are convinced he is, then there is no reason for you to believe anything he says, as no credence can be given to it. To base any argument on what he said can only be described as "silliness", unless it is supported by independent testimony from more credible witnesses. His claim that he killed Joanna in her flat is not, in fact, supported by any other evidence at all.
