Patrick Swayze & Wife Dancing At World Music Awards 1994

Can my Limewire music be seen from the authorities when I download from iTunes?
I have been using limewire for downloading music, but due to the things I hear about people getting sued I want to stop and download music the right way, iTunes. The only concern i have is if you use iTunes, can my hardrive still be accessed to see if I ever downloaded illegaly. Basically, if I download music from iTunes, can they see if I have limewire music on my iTunes? I would greatly appreciate help. Thanks.
