Well, you may be right that Amanda's courtroom testimony isn't credible, but that's the best we have to go on as regards her knowing Rudy:
CP: Good morning, Miss Amanda, I am Carlo Pacelli, I am the defense lawyer for Patrick Diya Lumumba. A little remark: I will try to keep my questions in simpler Italian. May I start?
AK: Thank you, yes.
CP: You know Rudy Hermann Guede?
AK: Not much.
CP: In what circumstances did you meet him?
AK: I was in the center, near the church. It was during an evening when I met the guys that lived underneath in the apartment underneath us, and while I was mingling with them, they introduced me to Rudy.
CP: So it was on the occasion of a party at the house of the neighbors downstairs?
AK: Yes. What we did is, they introduced me to him downtown just to say "This is Rudy, this is Amanda", and then I spent most of my time with Meredith, but we all went back to the house together.
CP: Did you also know him, or at least see him, in the pub "Le Chic", Rudy?
AK: I think I saw him there once.
CP: Listen, this party at the neighbors, it took place in the second half of October? What period, end of October? 2007?
AK: I think it was more in the middle of October.
…….
CP: On the occasion of this party, Miss, was hashish smoked?
AK: There was a spinello that was smoked, yes.
CP: At that time, in October 2007, did you use drugs?
AK: Every once in a while with friends.
CP: Which substances were they?
AK: Marijuana.

Paul the Private Eye obviously didn't believe Amanda either, as a week after her courtroom testimony, he stated on nationally broadcast CBS: "
Amanda and Raffaele never laid eyes on Rudy, never met with him and never hung out with him... didn't know him."
