New Presidential Directive

I am very disturbed to hear about a recent directive signed by President Bush in which he declares that, in the case of an emergency or crisis in which large numbers of Americans are in danger, the executive branch of the government will coordinate the running of the continuity government. Now, clearly, it seems wise to have plans to ensure that the United States government will continue to exist if Washington, D.C. is attacked. Apparently, President Reagan's administration first created a continuity-of-government plan, but, in Reagan's plan, the agency in charge of ensuring continuity was FEMA. Until this new directive, the agency in charge was the Department of Homeland Security. Why has this plan been changed? I try not to think about conspiracies, but this directive makes me wonder.

Here is the directive: http://www.whitehouse.gov/news/releases/2007/05/20070509-12.html
