知らん！（爆）

ここ2～3日，Podcastやいろいろな所で聞こえていて，正確に何を言っているのか気になっていた，ラムズフェルトさんの名台詞，BBC様で見つけたので，ちょっとお借りします。

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.
