Assuming that the fundies are intelligent would they not want to provoke what you are saying in an attempt to open a battle on a second front? It seems to me that they could also divide the country by having a sympathizer use the right implements in a terror attack, call it a "Columbine for God." Do the fundies drop a second shoe, if so, when?
An old blame-the-Jew trick from mediaeval Europe was to declare that all widespread illnesses were from Jews poinsoning the water wells. It always worked. Pogroms, you know.
I look for water systems being tampered with, to achieve scarerism in a very cheap stab at terrorism. One or two real poisoning would produce the desired result. If executed only in towns with mosques, Islam will get the blame and the terrorists will get the blame. Success for terrorism.
Y2K should have taught us all to have stored water in the house, 10 gallons person. The Red Cross's guideline is at a MINIMUM have 10 gallons for two weeks. I'd bet that less than 5% have such survival stores.
