FEMA is supposed to get ready ahead of time for any possible natural disaster that might happen; that includes predictable hurricanes in late summer and winter weather events soon after that. They don't know where they're going to happen, how bad they are going to be, how many will be affected nor how many events will happen in any given year. A good plan would design for 'worse case scenario' up to and including hundreds of thousands of caskets or burial enclosures for mass burials in the event of a major disaster like Katrina or a flu pandemic. It's only a matter of time until the next version of the Spanish flu gets past initial containment and this time over 100,000,000 people can be expected to die and long term quarantine cannot be expected to work without food and water supplies in place in advance.
Here's an interesting read about the legal and logistical issues associated with disease containment: http://www.ncbi.nlm.nih.gov/books/NBK54163/
Also, just as a personal aside, I worked for a major big city hospital (Portland Oregon) back a few years ago when one of the seasonal flu scares came about. My job duties and scope of training was as a transcriptionist, which is basically a glorified word processor and medical records clerk. Although I long ago had nurse's training, that was certainly not part of my current training.
Word came from on high in HQ that if a pandemic happened, we would be expected to report for duty in any department, for any kind of work needed, and for any amount of hours necessary; this of course was to 'cover' the emergency room as well as other departments when and if the available doctors, nurses and other technicians had either succumbed to the disease themselves, or elected to stay home and take care of their families... all my co-workers were aghast and ridiculed the very idea; not only were we not trained, but the percentage that would volunteer to come to work under those circumstances of a virulent easily transmissable and fatal disease was very low.
In essence, your local hospital expects to keep the doors open using untrained staff once the trained staff is no longer able to work; this isn't viable planning, it's whistling in the dark and a fantasy. (Keep in mind that a rapidly advancing flu like H5N1 kills by internal drowning within hours; the only hope is strong antibiotics and respirators; the largest cities have only a few dozen respirators on hand and the need would be in the 1000s almost overnight. Who gets a respirator? A baby? A fellow doctor? The hospital benefactor?)
While preplanning is necessary and not overtly worrying, a lot of the preplanning will end up useless or worse. Of course, the only possible use for bullets would be in the event of mass chaos and civil disorder on a wide scale. What's that saying? That civilization is a thin veneer that will end after three meals are missed?
