Maybe if it was handled correctly there wouldn't be an annulment
If the evidence had been handled correctly and Kercher's DNA had been found on the blade of the kitchen knife things would certainly look very different. However the prosecution case is so full of holes that it seems extremely unlikely there was ever any of Kercher's DNA on the knife.
I don't believe he (Guede) has a record for anything
He has a conviction for being in possession of stolen goods.
We know AK tried to get an innocent man done for murder
After 50 hours questioning over 4 days with no lawyer present, no recording of the interviews and with an interpreter who apparently believed her role was to assist police rather than simply interpret Knox made statements in the early hours of the morning (1.45am and 5.45am) implicating Lumumba. At the time the police believed Lumumba was involved. It is common in miscarriages of justice to find that the person convicted has been pressured into making false statements which coincide with the current police theory at the time but are subsequently found to contain major factual errors. Knox's statements were ruled inadmissible for the murder case. It would be far more accurate to say the police tried to get an innocent man done for murder.
In the UK it would not have been possible for Lumumba to sue Knox for slander. In Italy he was able to do so. However, in order to pursue this case he had to change his testimony. He was initially very supportive of Knox and claimed he had suffered serious mistreatment by the police, very similar to the claims made by Knox. It was only when he was unhappy with the compensation awarded for wrongful imprisonment that he turned on Knox. Much of the things he now says are directly contrary to evidence he gave in court. Note also that he was reportedly paid 70,000 Euros by the Mail on Sunday for an interview.
This looks like a wikipedia page. Is it?
No. It is a site using the same software as Wikipedia which therefore has a similar look and feel. The site is run by people who clearly believe Knox and Sollecito are guilty and will ignore any evidence to the contrary. It contains many inaccurate statements. The "myths debunked" page is itself full of factual errors. As far as this site is concerned the report of the court-appointed independent experts doesn't exist. This report thoroughly discredited the DNA evidence. It ignores the fact that the courts said the police were wrong to interview Knox without a lawyer. It ignores the fact the court criticised the behaviour of the interpreter during Knox's interrogation. It implies Knox's interrogation was only 2 hours long and ignores the previous 40+ hours of interrogation, much of it in the early hours of the morning. I could go on but there is little point. I do not regard this site as having any credibility as a reliable source of information.
