Who is talking about legislation?

Are you adjusting your perception of the problem based on fear of a possible solution?

Anyway, our society has fuck tons of protections against "what ifs" that are extremely good, actually. We haven't needed a real large scale anthrax attack to understand that we should regulate anthrax as if it's capable of producing a large scale attack, correct?

You'll need a better model than just asserting your prior conclusions by classifying problems into "actual threats" and "what ifs."
