NY Times editorial called the decision of US v Williams:

In the dissenting, Justice Souter writes in the last para.:

Perhaps I am wrong, but without some demonstration that juries have been rendering exploitation of children unpunishable, there is no excuse for cutting back on the First Amendment and no alternative to finding overbreadth in this Act. I would hold it unconstitutional on the authority of Ferber [1982] and Free Speech Coalition [2002].
