Slight Exaggeration?

Am I the only one who thinks the current U.S. government exaggerates the internal threat from terrorists just a teensy weensy bit? I mean they go totally berserk when they think they have discovered a single Al Qaeda cell. Imagine what would happen if they actually found an Al Qaeda organ, or heaven forbid, an entire Al Qaeda body. But no, just a cell is enough to freak them out. I guess they must be worried about that terrorist DNA, although I tend to think that more attention should be payed to the environmental factors that cause it to be expressed.
