From the Boston Review a must-read Noam Chomsky lecture What We Know On The Universals Of Language And Rights

Which brings to mind the segment at the end of Downfall where Traudl Jung (Hitler's secretary in the bunker) admits grudgingly that not knowing was no excuse, if it wasn't then it's even les so know.

...I have become satisfied that I had no personal guilt and that I knew nothing about it — I knew nothing of the extent of this. But one day I happened to pass by the memorial plaque for Sophie Scholl which was put up in the Franz-Josef-Strasse [in Munich] and I saw that she was born in the same year that I was, and that, in the same year that I started working for Hitler, she was executed — and in that moment I actually felt that being young is no excuse, and that maybe one could have found out some things.
