Responsible Media, Where?

Okay - some in the media are now being held accountable for their actions!

Instapundit has this:

The opinion is here. (Via Baseball Crank.) Maybe we'll finally get to the bottom of the "who leaked" scandal once the press -- which has known all along -- tells us. Earlier posts here and here.

Yea, why didn't they just tell us all along? Isn't that their job? Or am I just confusing what a responsible media would do!
