Whatever happened to the patriotic journalists?

Remember after 9/11 and during the run-up to the war in Iraq, when, led by Fox News, all the TV anchors and commentators went out of their way to show how patriotic they were? Remember them wearing their flag pins and claiming to be Americans first and journalist second? Yes, those were great times. I guess that's why I find it so odd that no journalists are coming forward to reveal their sources in the Valerie Plame case. Shouldn't a true American patriot want to help his country find this illegal leaker, instead of hiding behind journalistic ethics? I guess we've found the limits of patriotism.
