Ashcroft v. ACLU leaves a big problem unsolved

When the Supreme Court issued its decision on 2004-06-29 in the case of Ashcroft v. ACLU (regarding the Child Online Protection Act, or COPA), I whipped off a quick, rather florid op-ed to the Minneapolis Star Tribune. They don’t seem to have run it, so in case anyone finds it interesting, I’ll post it here. The gist of the argument is the same as that I made five and a half years ago in a commentary in the Communications of the ACM.
