I can't believe you are so naive as not to see that evidence for what it is.
Imagine this scenario:
Neither Raf nor Amanda murdered Kercher. Both spent all night together, making love or whatever after 8.40.
The police become utterly convinced Amanda is the killer with Raf the accomplice. There is some evidence of Amanda as killer.
Your lawyer tells you there is enough evidence to convict you both.
You are Raf.
Do you:
a) stick to your story and go to prison for a murder you didnt commit
b) detach your story from that of Amanda's (by being more vague about the details), so any evidence linking her to the crime is less likely to be applied to you, and thus lessen the chances of going to prison for a murder you didnt commit.
Tell me that it isn't perfectly believable that someone would pick option b) (morally rightly or wrongly) in that nightmare scenario.
