Nothing like a properly frightened society - ready to run screaming like a well trained dog.
Meanwhile, "innovators" like Mosanto have been quietly poisoning your food, land, air and water, and who gives a damn? Nobody. Even Coca Cola has killed more than all terrorists combined via diabetes and obesity-related problems, but if it does not look like a threat, well, it's probably nothing.
Meanwhile - a bomb - whoooo, scary thought. And even though some of us were not there, we might at least talk about it, and psych ourselves up, so that we can panic properly next time.
Better install more cameras, and increase NSA budget. And manufacture and sell more guns. Frightened people armed to the teeth often form safe societies to live in.
