FEMA Coffins and CDC conspiracies!?

Ok so my roomate is great but sometimes she gets really into some wild conspiracy theories. Don't get me wrong I put some stock into the occasional conspircay theory if it makes sense. This one is a new one for me, FEMA coffins and concentration camps lol. My roomate things this is for malicous intent but I think its one of preperation for events such as Katrina. She thinks the government is going to put mass amounts of people in concentration camps then kill them hence the mass amount of coffins. I think its for incase natural or man made dissastor. With any catastrophic event massive death tolls can happen, so you have to disspose of bodies, lots of them. If you don't this can cause disease, many super bugs were brought about by improper management of decaying bodies. A little impersonal I know but sometimes s#@t happens and we have to act quickly to prevent more death and disease.Or maybe its for an upcoming zombie invasion, the CDC does own the coffins and they did put zombies on the list of possible dissasters, we can only hope :)! Heres a link to the FEMA Coffins for anyone curious or if you just want to become paranoid. http://www.youtube.com/watch?v=m3zSDdm-SHI
