I believe that this is the case. There are already provisions in place to deal with sites within the juridiction of the DoJ. The primary affect of the bill is to give powers to those 'injured' parties seeking recourse against those sites thought to be distributing copyrighted material. The bill ( from my reading, I could be mistaken ) grants no new power to deal with domestic sites beyond amending the definition used in conjunction with already existing laws. Specifically section 2319 of title 18 of U.S. Code.
