don't know, do not know
カメラを向けても知らぬ顔
Even when I point the camera at them, they act like they don't notice.
— ベルリン・天使の詩 (1987)
知らぬ者がいようか。
Who could possibly not know?
彼らは知らぬふりをした。
They pretended not to know.
知らぬふりをするな。
Don't pretend you don't know.
いつの事かは誰も知らぬ
No one knows when it happened.
— Бриллиантовая рука (1969)
