I grew up in a town that was aout 30% Jewish. It was not unusual to see parents, grand-parents, uncles, aunts, etc. at my friends houses who had the tattood fore-arms.
In 1979 I was commissioned to write a short fund-raiser film for the Holocaust Musuem. I interviewed a number of survivors who had spent their childhoods in the 'care' of Jumper's buddies.
There's nothing like hearing a woman tell the story of being sodomized by a guard at the age of nine...of killing another girl with a knife at the age of eleven so that she could steal a potato to give to her sick sister (who was gassed a month later anyway). An eleven year old murdering another child for a potato --- one of Herr Jumper's "hungry mouths to feed" that the Germans were so afraid of.
These people told me all I ever need to know about Herr Jumper's poor mis-understood compadres.
For those irrational guys looking to slander me, I spent 20-years as a paratrooper and 8 more as a diplomat, so I understand the shallowness of callow rants/raves. My wife was the America representative to Israeli Govt for the Arrow Missile Program heading up the US Army field office in Tel Aviv. I am the last person to hate the chosen people of the bible or support crimes against humanity, and the diplomatic side of my experience understands the irrational feelings and one-sidedness the comes from people dealing with subjects they have neither researched but have strong opinions none the less. Cheers.
