Pardon me?
To boycott a country (esp one which is as beautiful and friendly) as Italy, a pro-american nation BTW, because they jailed an American?. Even if you think the verdict is wrong, to boycott a country just because of that is silly.
Do I boycott America because OJ didnt get sent to prison or that I was appalled at the Rodney King officers acquittal?. No, of course not.
