What the hell is this all ablout:
"Reports that say that something hasn't happened are always interesting to me because, as we know, there are known knowns; there are things we know we know.
"We also know there are known unknowns; that is to say we know there are some things we do not know.
"But there are also unknown unknowns - the ones we don't know we don't know."
Now who would say a thing like this??
