I think this discussion should be on the way EOs have federalized everything. Its not tinfoil to want to keep authority with the local government and citizenry, and not give it unconstitutionally to the federal government.
While I agree with you in theory, I'm not sure how well it works in practice. For example, with Hurricane Katrina, the local government failed miserably with its primary responsibility, guaranteeing the safety and welfare of its constiuency. With that in mind, it only makes sense for a superceding authority (the fed via FEMA) to take over in the restoration of domestic tranquility. This is really the same reason that we have a republic as opposed to a direct democracy, so that more distant and cooler heads can prevail in times of crisis. Of course, issues that are purely local are best handled directly without undue external influence.
If I have any disagreement with the fed on this issue, it's that they didn't assert their authority more quickly when they were obviously aware of the dysfunctionality of both the city and state level in Lousiana.
