For later
I do the 72 hour thing, not a prepper by a long shot. I am armed, practice weekly with my guns, and can last a while hunkering down in teh home front. I went through Katrina so I have an idea of what I needed.
I have camping gear (propane stoves etc), fire starting tool, knives, some water put away.
My wife is a nurse, not a psych nurse, ER, and we discuss those people, they all really need psychiatric help. The new york fire fighter, you can guess why he has a psychosis. Some of them really are undiagnosed schizophrenics and compulsive behavior issues.
Its possible to prepare for an emergency without going as far as they go. I mean the Zombie Uprising is my biggest worry, and I am prepared for that :)
