I've been following Amanda Knox's case for years. (I even took students to one of the courtrooms in Florence.) The lesser-known charges were criminal defamation of police (overturned) but years ago she was convicted of that crime when she mentioned a bartender as a possible suspect. Recently, the European Court of Human Rights ruled that her confession was coerced so she just went back to court to clear that – a decade ago, she was sentenced to 3 years (but got time served since she was in jail for 4 years) and then left the country. The lower court just ruled against her. (There will be an appeal.)
In Internet Law, we go over some country laws of criminal libel.
