How exactly does the RIAA get the evidence that they need to charge someone with stealing music? Do they send viruses over the file sharing programs, or have a computer sharing files and track who downloads from that computer? Do they search message boards looking for people admitting that they have stolen music? And most importantly, what did the people who got caught do to get caught? Out of an estimated sixty million "song stealers" only a couple hundred/thousand have been charged. So I guess those people must have done something in particular to get caught.
