actually depends on how the police track you down. if they plant
spyware in the mp3 you download, whatever you do is
useless...
if they use a torrent client to scan thru all the local ip and
start tracing its owner, you can avoid being detacted by using a
oversea proxy...but the downloading will be so slow that i suggest
you dun waste your time downloading.....
But, please DO NOT download at MacDonald thinking you are safe....

IMO, if you have tons of downloaded mp3/softwares in your harddisk,
you better stop downloading....if you are caught, that's it.....its
gonna cost a bomb
