Seems to me this is going off track a little. He's been arrested and faces deportation. He was a camp guard - there to train others in the use of dogs....he was there a short period then moved on......these appear to be facts (if the article is to be believed (i'm cynical about papers etc)).
I can see no mention that he actually released his dog onto prisoners, nor any mention that he killed/beat/starved any either - so this would appear to be speculation.
If he is guilty....punish him to the maximum extent - what was done at these camps was beyond evil - Nobody deserves to be treated that way!
If, however, proof cannot be found to show he did carry out any atrocities - he should be left alone.
So far, the argument that seems to be raging is a bit pointless, speculatory and inflammatory - carry on, I've got my popcorn and a nice coffee (cant drink at work ho hum).
Just my 2p's worth.......
