i'm partial to this story

"I once saw DPs(displaced person) beat an SS man and then strap him to the steel gurney of a crematorium. They slid him in the oven, turned on the heat and took him back out. Beat him again, and put him back in until he was burnt alive. I did nothing to stop it. I suppose I could have brandished my weapon or shot in the air, but I was not inclined to do so.
