Although we here see the Democrats as the Party of Government, the bureaucracy itself sees itself as non-partisan. Controlling what the people know is more important than mere party politics. FEMA as an especially unaccountable bureaucracy, sees nothing at all wrong with manhandling the truth if it is in their plan to handle disasters on this scale.
The lack of candor we see here will only be multiplied if something with evil intent behind it happens. Do you think, for example, that you can trust the government if there is a bioterror attack?
The MSM all owe their existence to FCC licensing and government permission to be exempt from anti-monopoly laws. They WILL obey when told what to say and not say.
