I know where I stand on this. I'm behind the government and I'm tired of First Amendment shilly-shallying that fills my children's Hotmail screens with dozens of porn come-ons every day. But I will defer to Justice David Souter's eventual opinion in US v. ALA, (1) because he cares about the First Amendment in an intelligent way, and (2) because it was once said of him, correctly, that ''he regards Boston as the center of the civilized world.''
