"In his book 'Ordinary Men: Reserve Police Batallion 101 and the Final Solution', Christopher Browning studies the actions of a German police squad that killed thousands of Polish Jews during the Second World War. The squad consisted of ordinary men: none them were hard core Nazis, none of them were exceptionally violent, none of them had volunteered for the mission, and none of them were especially trained. And yet a majority of them quickly became ruthless and efficient killers. How, Browning, asks, was this possible?"
