My argument against a national shield law is up on NRO. In it, I talk a lot about the culture of leaks at the CIA. Since submitting it, I found that the Powerline guys have also been tracking this debate. Too often in the debate over the shield law, conservatives associate the law with it’s most vocal champion, Judith Miller. They shouldn’t. They should instead remember that before Bob Novak ever named Valerie Plame, Joseph Wilson was an anonymous source leaking information to the press.
