Word is, just now, that USCG Vice Admiral Thad Allen will be taking over on-site management. This sounds like a good move to me, from both a logistic and political standpoint.
Update: in response to some commenters: I really think that, politically, Honore would have been a MUCH better choice. And, this situation having become so politically charged, politics accounts for much. The fact that the designee is a military person amounts to little: public opinion on the military is totally bipolar – either they are saints, or Satan’s Slaves.
