The US and bittorrent
 

Have anyone been sued in the states from downloading music and movies with bittorrent?
Or is it just kazaa, direct connect and such that have been targeted?

yes someone has been sued . .cant telll no names though . .thats highly confidential ..

Have it been tried in court?
Is it safe for Americans do download and share thru bittorent?

no, Activision won a court case against it last month for sharing games

they cant sue you if they cant see you

BitTorrent, if the unencrypted protocol, is quite easy to sniff and obtain data for. There are plenty of 'fake' BT clients. I have no idea what your chances are, but I sure as hell wouldn't tempt it.
