Not to belittle anyone, nor doubt the veracity of the actor's claims, but if MY family had been killed by Nazis, I'd have a problem wearing the helmet, uniform, and in general, even "just playing the part". After you've gone that far, why quibble about a rifle? Following the logic of "in for penny, in for a pound", I find the actor to be a trifle disingenuous. He played the part and took the cash, so what's the point?
