 The defense argued that Thomas-Rasset had no reason to download music, as she was one of the plaintiffs' best customers, having legally purchased over 200 CDs, including many of the songs at issue, which she only ever ripped into WMA format, not MP3 as found in the shared folder.On the stand, Thomas-Rasset speculated that perhaps her children or then-boyfriend had installed Kazaa on her computer without her knowledge.Closing arguments focused on the fact that none of the evidence pointed to Thomas-Rasset personally, but only to the IP address assigned to her Internet account.
