Wednesday evening I attended a panel in Manhattan discussing bioterrorism, the most memorable part of which was one of the experts' reply to a pretty straightforward question (both of which I'll paraphrase). The question: You're both medical professionals. If you really wanted to kill as many people as possible, what would you do? The steel-tipped answer: I would withhold condoms and clean needles from people at risk of contracting AIDS. Nicely put.
