OK.....
So, if this guy was a guard in a death camp - and they can prove it - what are they going to do to him?
Put him in a maximum-security nursing home?
Nazi hunters.... give it a rest already.
Hanging his ass is too good for him if he is guilty.
Dude, I'm not Jewish and I don't really have a dog in this hunt, but really: go to Germany or Poland and look at the facilities, look at the ovens, look at the blood-stained carts for corpses, look at the hundreds of pictures. Walk the earth where this happened and feel the souls.
Then tell me to give it a rest.
