"Wink, wink, nudge nudge; I'm not telling you you to spy on this list of people, but it sure would be convenient..."
As with every other time we mention NSA, if you're going to assume they will break the law as a matter of course then you must leave the Internet immediately or face spying. :P
On the other hand if you want to posit that being easy to break the law is reason enough to burn all the transatlantic fiber so that GCHQ can't cooperate with NSA then simply say so, it's at least theoretically a defensible starting point for a debate.
