you have to understand their lies, they have a methodology to them
“not familiar with” means, to most people, “knows nothing about”
but to the liars, it can mean,
“I’m not (just) familiar with it, I know all about it (since I ordered and am in charge of the cover-up)....
Or taking "familiar" in the sense of "informal" -- he's never informal about it, but always deals with it formally. Then he isn't and will never be familiar with it.
