"I always thought this would be a good way for terrorists to initiate a second attack, by distributing contaminated/laced medicine/food/water through a volunteer network."

Do you think terrorists are likely to be that subtle?

It seems to me that people of the terrorist mentality are more fond of explosives and guns. You may be right, but nothing I've heard about terrorists has indicated that they even think of operating in low-key mode.

Speaking of the pseudo-anthrax incidents after 9-11, I always thought of them as instigated by good old American citizens who thought it would be a good joke. Were any of those people found? And if there were, did any serve jail sentences to readjust their sense of humor?
