We don't need to invoke the Alien and Sedition Acts, and we don't need to start prosecuting journalists. We need to force our elected Congress to collectively grow a pair and haul Bill Keller and his pals before them to explain themselves and reveal their sources. Keller has unilaterally usurped their authority and is threatening our entire Constitutional sytem of government. He cannot hide behind the First Amendment if he is called by Congress to explain himself and forced to reveal his reporters' sources. The best attack on the NYT et. al. is to show the American people that a tyrannical press with a political agenda is the biggest threat to our liberty.
How about a massive protest urging those left to cancel their subscriptions?
