As for the original question, I don't plan for any scenario (short of a hurricane, since we get hit 6- 7 times a year). Instead I just have the equipment and supplies to react accordingly. I haven't thought of (or supplied for) everything, but what I have will give a good head start in a catastrophe.
Re the biological weaponry. Most is designed to become nonlethal in 3-5 generations (i.e. times the virus/bacteria mutates). Reason being they are designed to eliminate ot "take the fight out" of populations, so an enemy can move in and use the resources without having to fight for them. Terrorists would probably get their hands on military grade stuff. Terrorists sitting in multi-trillion dollar underground command centers and weapons labs creating doomsday weapons are the stuff of James Bond movies, not real life. That's what governments do.
Oops, there goes another night's sleep eh?
