Absolutely not true.
"FEMA is tasked with responding to, planning for, recovering from and mitigating against disasters." that is from their own website. They did a horrible job until recently. FEMA can step in and take over anytime they want ecspecially since 9/11 and they are in the Homeland Security Department. They over rule local authority of which I do not think they even knew. They need to read there own site.
Only a liberal would post that on this site; most of it is just out and out lies.
They do NOT 'take over" at any time.......they have to be ASKED IN by the local authorities.
The rest of your post is too ill-informed to respond to.
Just a word of advice, we expect facts here -- not just liberal talking points and boilerplate remarks.
