In case you're an Olympic athlete and you wanted to bring your posse along to the Winter Games in Turin next February, the Italian govt has issued the following statement: Vietate portare. Apparently, the Italians are more than capable of handling the security.
That's because the Italian military has a crack team of security specialists for the region. They are called the Alpini. I'd advise you not to mess with them, particularly when they play "When the saints go marchin' in."
