The 1972 killings of the Israeli athletes is 43 years ago. It's quite likely anyone under the age of 50 has never heard of that tragic event...and if they have, won't remember it.
I remember in the version I saw, he kills an attractive nude German woman. With the bullet in her head she sits there dead with her legs spread.
He puts her legs together, I guess to hide her shame but his partner pulls them apart again, wanting to show her shame.
