The Italian Supreme Court has overturned Amanda Knox's acquittal and she's subject to another murder trial in Italy. Presumably she's back in the US now. Hopefully we won't allow extradition.
I am very glad that I don't travel overseas anymore. As Rocket pointed out, we lose our constitutional rights when we enter the air space of other countries. Granted a lot of our citizens that get busted either break their laws or just act in a stupid way (hiking in a war zone for example) but be prepared for a big culture shock.
