Snippy editorial from LAT

In a snippy editorial today, the LAT criticizes the Bush administration because Attorney General Mukasey wrote a letter to the Senate Judiciary Committee saying he wasn't going to share certain documents. Yesterday, President Bush said that the administration will cooperate with Congress in the CIA tapes investigation. The two things aren't necessarily contradictory but the LAT went on the attack anyway, suggesting Mukasey is getting his comeuppance. Why the rush to pronounce sentence? Why does the LAT not offer something positive? Is there something that the LAT wants to see done? Or does the LAT just want to bitch?
