Skip contrary to your "opinion" the evidence for the Guildford 4 was "sat on" or rather "deliberately suppressed" as the officer concerned did actually lie in court about his "altered" statement for 16 years before it was investigated by someone researching the case.
Therefore as the police refuse to reveal those files that are currently suppressed by the police under PI we must assume that there is further evidence that may contradict that evidence that was heard in court. Plus the fact that although you insist that there was nothing in the evidence that was destroyed in the 90's that would help Bamber, there is absolutely no way that you can know what evidence could or could not help Bamber.
Therefore we are entitled to hold the police's refusal to release the evidence currently held under PI under suspicion, for their very refusal is an indication of guilt on their part.
It is easy to tell none of the evidence destroyed could have helped Bamber. There are no indications of Sheila being wounded beyond the gunshots so obviously she would nto have gotten her blood on the victim clothing that was destoryed EVEN if she had been the killer. Nor would there be any hope of finding GSR on her gown they already tested it thoroughly and the only new testing permitted is by new methods not available at the time of the murders so only DNA tests. Non-blood DNA from Jeremy and SHeial could be potentially found on anything as a result of contamination such means nothing as to who the killer is. The only DNA test that could actually matter in this case would have been tests of the blood removed from the moderators that had been determined to be Sheila's but the tests done destroy DNA so they coudd not have tested that years later anyway even if the lab retained such.
The defense was unable to explain any other DNA test that could be of value and that the inability to do prejudiced the defense because there was no DNA testing they could have done to exonerate him. The only thing the defense could think of to test for DNA to try to exonerate Jeremy was a DNA test of the moderator but even that was invalid because the Appeal Court explained:
1) there was no way to establish such was blood based DNA which is what matters
2) even if blood based DNA of others had been found that doesn't establish that the blood previously removed and tested wasn't Sheila's. All that would prove is that other blood could have been there in addition to Sheila's not that Sheila's wasn't there and already removed.
in the meantime blood of any victim being found in the moderator means it was attached prior to the murders, used and then removed and put away after the murders. Why would Sheial go get it from the closet, and then put it back away? The fact it was used at all shows Jeremy is the killer.
What could have been altered from Jeremy's statements to change facts he claimed in order to try to convict him? There was no need to alter anything. Jeremy testified and gave his own account of things which was the same lousy account in his statements.
It is astonishing that someone who supposedly was so involved in trying to help Jeremy is so amazingly ignorant of the basic facts of this case. you basically mad eup your mind he is innocent from a position of ignorance and just spout worthless myths to try to sugges the is innocent. To be an effective advocate you have to be acutely aware of all the relevant facts and evidence. Your ignorance explains 2 things it seems:
1) why you think he is innocent (because you don't know why he was even convicted and just assume the evidence was insufficient)
2) why you are so ineffective at helping him.
