One of the key responses from the NSA and its defenders to all of these Snowden leaks is that there is „rigorous oversight“ of the NSA by the courts and Congress. Of course, that talking point has been debunked thoroughly, but NSA defenders keep trotting it out. It appears that the public is not buying it. At all. A recent poll from YouGov found that only 17% of people believe that Congress provides „adequate oversight“ on the spying of Americans.
