In addition to the Katrina falsehoods you mentioned, here's a few others:
They reported that John Paul II died some hours before he passed.
They reported that a document prepared with MSWORD was typed in 1972.
They reported that Florida voted for Gore in 2000.
They reported that Joe Steffen spread rumors about Martin O'Malley using FR, and they did not report that it was a RAT operative whose account they accessed who actually spread the rumors.
They reported that Valerie Plame had covert status with the CIA.
Need I go on?
Wonder how they'll handle a dirty-bomb going off in Manhattan?
