How do you construct an "independent group"? Who chooses the people in this group? If it's the government choosing, then it's not independent. If people can choose for themselves to review this sort of stuff, well, that's what Snowden did.
What is your scheme to ensure that all of the people who need to review (which should be millions, right?) are able to fairly review, without also exposing the stuff which should not be seen by ISIS to that review?
Snowden "chose for himself" just as much as John Walker "chose for himself" to figure out U.S. Navy anti-submarine doctrine during the 80s and pass it to the Russians.
