I admit the possibility of a conversational zero. I don't see much point in arguing over it. Given current information, I don't expect to even change my behavior over Ebola (but I'm not in Dallas and I already didn't have plans to travel to west Africa). That meets my hand wavy, just invented definition of a conversational zero.

I posted the link because you said resolute in saying the chance of Ebola spreading in the United States is "zero.". I figured it was fair for people reading that to have an easy shot at interpreting the video themselves.
