Uh, folks.... this FEMA "death camp" thing is ridiculous.
First, in the course of the video work that I do I've met a few of the directors of the different regions and many of the people in charge of FEMA services on the ground. I've been around these folks and their discussions for about 6 years and they are about saving lives in the event of an emergency and, increasingly, about finding ways to prepare for and prevent catastrophic damage to life and culture in the event of an emergency. ALL of the discussion has been about natural disasters and not terrorism or civil unrest. Granted, I spent most of that time with the region 9 folks (Hawaii, Washington, Oregon, CA and Idaho) and only passing time spent with any officials with the other regions.
Seriously, these folks couldn't get together a FEMA "death camp" if they wanted to. They aren't that together. FEMA's organizational culture is that of saving lives and preparing for natural disasters. These people are NOT killers, despots or anything of the like: they got into the job because they want to help people.
The Patriot Act put FEMA under the direct control of DHS and that is why FEMA is getting such a suspicious look these days. But that PDF details the logistics needed to supply communities with emergency supplies in the event of an infra-structure damaging event - be it terrorism or natural disaster.
Granted... it COULD be used to house civilian prisoners. I'm not saying that it is inconceivable - in fact I think it quite likely that the government and military is well prepared for civil unrest in the US. The folks in FEMA - at least the ones that I know - aren't the enemy. For the most part what they are trying to do is prevent the kind of horrid, incomplete and ineffective response that happened after Katrina.
(Which happened, in no small part, because DHS gutted FEMA's budget to pay for non-military expenses in Afghanistan...)
I think FEMA - which is an extremely civilian friendly branch of the government - is being set up to bear the brunt of anti-government sentiment. Even if FEMA Is now under DHS, do not make the mistake of thinking that the "Federal Government" is at all a single cohesive entity. Nothing, and I mean ~nothing~, could be further from the truth. I think anyone who works with government at any level would understand that and agree.
