From the Boston Globe:
Conservative friends have been sending me long, detailed e-mails about the government's response to Hurricane Katrina. They are all designed to place the blame on New Orleans Mayor C. Ray Nagin and Louisiana Governor Kathleen Blanco, while exonerating President Bush. These electronic messages have certainly been impressive and revealed previously unknown facts. After reading them, I acknowledge the timelines of what happened, when and who knew what, and when and who signed what and when. My friends are right that state and local government were the first lines of defense--and they failed. This represents a systemic failure of government at all levels.
While their details are valid and their points well made, these are merely the facts.
