I think that it is very clear that there has been a terrible miscarriage of justice, especially in the case of RS.
The only evidence against RS at all is the bra clasp. There is nothing else whatsoever.
But what about the bra clasp? Supposedly it has DNA from MK (as you would expect) and DNA from RS. The problem is that there are additional DNA peaks on the sample as well, so where did these come from? The prosecution have attempted to explain it away as "stutter" or noise, but it is clearly DNA from someone else. Going on the assumption that MK was in the habit of wearing clean underwear, the only DNA that should have been present if the prosecution's theory is correct would be that from MK and RS. The additional DNA must therefore have been introduced AFTER the murder, but from where? It is obviously contamination and I bet that if they had done their controls properly and tested the investigators as well they would have found who had mishandled the sample.
Remember that this particular evidence was collected about 6 weeks after the murder, and that it was no longer in the same place it had originally been in, which means that it's providence was compromised.
I think it is very strange that they find no evidence at all that RS was there, then they go back 6 weeks later, and suddenly they find something that supports their original theory.
Then later on, this piece of evidence is mysteriously inappropriately stored so that it is destroyed and can no longer be subject to further testing.
IMO what happened is that the sample became contaminated as a result of sloppy work. Perhaps by accident, perhaps by intention. In either event the extra DNA on the sample was effectively the smoking gun that would prove it. Someone in their DNA lab must surely have realized this, and certainly further testing on the sample would have resolved that question. But then all of a sudden the sample is "destroyed".
There is no question to me that this particular piece of evidence is highly compromised and should have been dismissed after it was destroyed as a result. It is mind boggling that an objective judge would even consider it due to the very real possibility of tampering.
IMO there is a pattern for this behaviour, where evidence that might contradict the investigators version mysteriously is no longer available for analysis.
Another example of this is the hard drive, which was destroyed while in LE custody. The contents of the drive could have been used by RS's defence. How is it even possible for this to happen other than extreme incompetence or deliberate act?
Then the initial interrogations, which should have been recorded and should have been conducted with legal representation, but were not. And all that is swept under the rug as if it is unimportant. But it is important, since the accused claimed they were subject to abuse in this time. If LE had been operating according to the law, there would have been records to show what actually happened. But there were not, and again there were not specifically due to LE actions.
These are just some of the many examples of malpractice in this case. The judicial system from the investigators through to the prosecutors through to the judges are all part of the same corrupt system, where they look after their own. There are some exceptions of course, some of the police officers questioned the evidence for example, but they were over-ruled. Hellman questioned most of the evidence and found it severely wanting, but he too was over-ruled, with the supreme court directing the next trial to put greater weight on subjective evidence rather than objective evidence.
No doubt the next supreme court session will do the same, unless there are new judges on it who prefer the objective review rather than the subjective, in which case the trials start all over again.
It is just a shameful travesty of justice IMO, and I really do not know how these people can go to sleep at night given what they are putting this couple through, and all for pride in their corrupt system?
If they want to claim that AK and RS did it, well then prove it beyond reasonable doubt. If they can't do that, then AK and RS should be released. Sending a young couple to prison for half their life simple so that you don't have to admit to the flaws in their justice system is obscene.
