Shays issued an apology ("The Congressman stated his full support and admiration for the officers of the U.S. Capitol Police and offered his apologies"), but not before embarrassing himself as a Capitol diva. A legislative Lindsay Lohan in a suit and tie. Reps. Shays and Filner are just the latest in a long line of Beltway Brat Packers, and they won't be the last. For the line-jumpers and elbow-jabbers in power, as I've said before, "public service" means never having to say you're sorry for behaving like a royal pain in the . . . buttinski.
