"Tetanus, typhoid ... will be just as effective in culling the looters."
I sincerely hope you're right. Because I doubt many, if any, of these sub-human vermin will be shot -- at least by the authorities. Our society is simply too steeped in political correctness and "compassion." One can hope that armed citizens will take matters into their own hands when need be, but I suspect they too are intimidated in these corrupt times.
