government style Ebonics

Huh? Quote of the week;

“REPORTS THAT say something hasn’t happened are interesting to me, because as we know, there are known unknowns; there things we know we know,” Rumsfeld told the briefing.
“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.”

This is a funny example of Donald Rumsfeld slipping and throwing some government ebonics out. Cause I can damn sure bet that anyone that’s been in the government sector knew what he meant.
