Who keeps an eye on Big Brother?
That used to be the reason for the first amendment and the inclusion of the "press" know more commonly known as the "media". So we no longer can count on them so where do we turn? See the 2nd amendment.
Who watches the watchers?
Take away the 2nd and the watchers have nothing to fear from the masses. I doubt the US government would follow a court injunction or congressional laws in this regard. Until a judge jails some US government employees or department secretaries or the congress closes the purse the government will do what it wants to and the law be damned.
