You're completely off the rails here. You've devolved back into discussing the probability of dying from a terrorist attack instead of a whole system analysis. Some questions to answer your questions. Do you think the government knows things about the economy they don't release to the public but use to inform their monetary policy? Do you think the same might be true for terrorist attacks and their security posture? Does the fact that you don't know something mean that it is inherently unknowable?

So your answer is that you have no idea what the chances of a major terrorist attack are, and no way of finding out, but you think the government does, because they have secrets.

Well, there's no way for me to argue with that. Good talk.
