Nagin requests National Guard!?!

I thought that I was reading a recycled headline (from nearly a year ago) when I read "Nagin requests National Guard Assistance." But it appears that notorious N.O. Mayor Ray Nagin is reverting to old form again: he has reportedly requested that National Guard troops be sent in to N.O. to help maintain order after five teenagers were killed there in a shooting over the weekend. Mayor Nagin, it seems that N.O.--with a greatly-diminished population and billions of dollars thrown its way, should be able to maintain its own police force. This only accentuates the problem that Nagin has, I perceive, in passing the buck when times get tough.
