Amanda Knox

I want to believe in her.  I DO feel badly for her.  But I think she did it.  I watched her interview last night with Diane Sawyer, and I found her very unbelievable.

But then again, I thought that Casey Anthony was guilty as sin.  And OJ?  Thought he was a goner as well.  So my reading on possible convicts must be wrong, right?  There couldn't possibly be a glitch in the US Justice (or Italian, whichever the case may be) system.  Could there?
