Google's eight-month-old think tank, Google Ideas, is paying for 80 former Muslim extremists, neo-Nazis, U.S. gang members, and other former radicals to gather in Dublin today, to discuss what draws people to violent extremism and how technology can carry out de-radicalization efforts. Google is calling the group "formers," and they'll be participating in the talks with 120 activists and business leaders. 

John Demjanjuk has been found guilty of being an accessory to murder as a Nazi concentration camp guard. He was living as a retired autoworker living in Ohio. In 2009, he was deported from the U.S. for a second time and sent to Germany, where he was charged with helping to force nearly 28 thousand Jews to their death at the Sobibor death camp in Poland. Reporter for the BBC, Steve Evans was at the trial.

Alice Herz-Sommer celebrates her 107th birthday today. As if that weren't enough of a an accomplishment, she also happens to be the oldest living survivor of the Nazi Holocaust. Her love of music inspires her to live her life with optimism and faith in the human spirit, even though she lived through one of the most horriying ordeals any human can imagine. Vincent Dowd, arts correspondent for the BBC, visits Alice to hear her story.

The suspected Nazi John Demjanjuk has arrived in Germany today where he faces a warrant accusing him of being a guard at a Nazi-run internment camp during World War II and being an accessory to the murder of 29,000 people. The retired Ohio autoworker was deported from the United States and arrived Tuesday morning at Munich's airport. Now the 89-year-old will be brought before a judge and formally arrested.

In the 1980s Demjanjuk was extradited to Israel where he was convicted of war crimes and sentenced to death; his conviction was overturned by the Israeli supreme court which accepted his claim of mistaken identity. But Demjanjuk has remained at the top of the Simon Wiesenthal Center's list of "most wanted" Nazi war crimes suspects.

For more on this story we turn to Tristana Moore, the BBC’s reporter in Berlin.

It has been over sixty years since the end of the Third Reich’s reign of terror over Europe and the Nuremberg Trials that followed. Yet the hunt still continues for the long-lost Nazi war criminals. So when alleged Nazi prison guard John Demjanjuk was found in a small American town, there was a thrill of victory for some and shivers for others. But despite what Mr. Demjanjuk may be guilty of, he is a sickly 89-year-old man. And for that he was given a stay of deportation Tuesday, just hours after immigration agents physically carried him in his wheelchair out of his house. Demjanjuk awaits a war crime trial in Germany. His family and lawyer said that he is so sick, a trip could kill him.

For more on this story The Takeaway is joined by David Marwell, Director of the Museum of Jewish Heritage. David followed Demjanjuk’s deportation and trial in Israel over twenty years ago. We are also joined by Jonathan Silvers who is finishing up his new documentary, Elusive Justice, about the search for and prosecution of Nazi war criminals.
