[A] major concern with ACTA’s very nature is that it is being designed as an “executive agreement,” rather than as a “treaty.” Executive agreements do not require Congressional approval before they may take effect. As a result, there is little to keep the signatories accountable to the public, especially in an election year that will see the departure of the current executive.Lovely. Not that Congress has a good track record on this sort of thing, but the public scrutiny that comes with Congressional oversight might not be the worst idea in the world. Hopefully some of the other democracies involved will have a bit more openness, though I'm doubtful.
In any case, Cory Doctorow put up a very nice presentation on exactly why you should be running around and shouting about this thing. Enjoy.
