Secret Service listening to Eminem lyrics for threat to president

Secret Service listening to Eminem lyrics for threat to president. It states in the article that this is an unfinished song and it was lost or stolen. Me thinks the government is using P2P ie. Kazaa or limewire, to search for what they consider threats, which is a no-no now a days. And if this was a stolen the RIAA should step in and sue the Secret Service for having the stolen song, just like they sue innocent people for sharing their music on the net.
