Yes. The Jews who died in Jedwabne, despite the Polish Institute of National Remembrance report in 2002 saying 340 Jews were killed by Poles, were actually all killed by Germans.
Dude, WTF is wrong with you? Were you born yesterday?!
Poles are openly blamed for holokaust, for being worse than Nazis, for being willing collaborators of the Nazis (mind, word GERMAN is never used), for killing eleventy gozillion of Jews, for all pogroms in history of mankind - and this BS is presented as 'it is widely known' by my-daddy-told-me scholars.
Sure, Poles were there. So were the bullets from GERMAN machine gun(s).
