So you are comparing civilian war protestors to Al Queda terrorists? Well I agree that even anti-war critics today have a congruence on preferred results with the Al Queda in Iraq, yet Napolitano is wrong, constitutionally, because the Al Queda terrorists do no become "domestic political opponents" just because they get a phony US visa and make cell phone calls from Boston and Florida. Technology and porous borders may allow foreign enemies to conduct their terrorism plans from our own soil, but they are still a "foreign threat" and when we track them from Jordan to Hamburg to Miami, the nature of who they are and what they represent, and what the law allows us to do, has not changed. Yes, when foreign enemies come here and we know they have come here we will "spy" on them, even here.
Then go to a judge & get a warrant for such spying....I have no problem w/ that for the most part.
