Kim Philby got away with it because he was posh

The story of Kim Philby is, of course, like so many English stories, really one of social class. He was one of the most scandalous traitors in history, and from within the security services sent specific information to the Soviets during the early years of the Cold War that resulted directly in the deaths of thousands of men and women. Among them were the Albanian guerrillas, hoping to liberate their country, who found Soviet-sponsored troops waiting at their landing places to shoot them. A list of non-communist opposers to the Nazis in Germany was passed on to the Russians who, advancing into Germany in the last years of the war, summarily executed 5,000 named people.

Philby worked for the British security services for years, almost all the time passing significant information to our country’s enemies. He was closely associated with those other traitors, Burgess and Maclean, and clearly helped them to escape.
