1.What I gathered was that the police saw Knox's text message to the bartender and then coerced a confession involving him. The fact that they got this confession when there is no way it could have been him suggests to me that much of the confession could be totally fabricated. For that matter, why would Knox name the wrong accomplice if they knew they didn't cover up Guede's presence at the crime scene?

1. One of my problems with the supposed cover-up is that if S and K were intoxicated during the crime and likely during the cover-up they A) wouldn't have been able to distinguish between evidence implicating them and evidence implicating Guede and B) wouldn't have been nearly as successful covering up physical evidence as they apparently were.

2. Perhaps Guede liked her and felt guilty. Part of the suspicion re: Knox was that she was insensitive after the fact. But this would be inconsistent with her covering up the body.

3. Knox was almost certainly seriously hung-over and not in the mood to go near fecal matter. Also, her roommates testified that she didn't do a lot to keep the place clean in general. I'm also not sure how not flushing suggests guilt.

Marijuana does not undermine rationality to that extent. Reefer madness PSAs considerably overstated that :-)
