That is big charge. Kennedy and Souter and Breyer and Ginsberg are still there making mischief. I guess that at least they are predictable and O'Conner wasn't.
Don't forget the mischiefmeister himself, Stevens. But I was distinguishing between bad judging and bad constitutional law. O'Conner was correct on the constitution more than, say, Stevens. But judges are supposed to draw clear lines so folks can predicate their behavior on those lines. That's part of the rule of law is knowing what the law is. O'Conner's decisions gave you no idea how the Court would go in the next similar case.
At least Stevens, Breyer and Ginsberg are clear: Whatever the ACLU wants to be unconsitutional, is. You can predicate behavior on a bad constitutional ruling.
