More interesting that CNN thinks they can read them but the public can not. Media organizations have no security clearances and thus are subject to the same access as anyone else.
Oh CNN.
Proving that those who say the media thinks they're above the rest of us are right.
There is also the famous Pentagon Papers case, which to my knowledge rests on the "freedom of the press" language in the First Amendment.
That said, this was a stupid thing for the CNN anchor to say. Regardless of the law, no federal prosecutor is going to waste their time trying to find and prosecute every U.S. citizen who visits the Wikileaks website.
It was about the printing press and the ability to print what you wanted and, just as importantly, not be forced to print the things you didn't.
