That will take you to the subpage on documents filed in this case. Near the bottom is a category, "Amicus Curiae Briefs." Click on the name, "American Civil Rights Union." That will pop up the only brief in this case that was filed by a FReeper, namely yer own Congressman Billybob.
The Supreme Court files (www.supremecourtus.gov) unfortunately puts its files up in PDF format. I believe that Stanford Law School has put the documents up in HTML format. I hope someone more computer-literate person than I will post a link to that brief.
