They'll just get a slap on the wrist by the courts and scolded by some members of Congress and then they'll go back to business as usual. Hate to be a pessimist because I don't think what the NSA does is right, but I can't really see how to stop it now when cell companies like AT&T are giving away customer info and software companies like Microsoft are building back doors into their operating systems specifically for government spying.
If the people ever find out that the Government went easy on the NSA, there will be hell to pay. This is a victory, mate! If the NSA acts again, let's kick them in the balls.
