Last July, one of the world's most wanted war crime suspects, Laszlo Csatary, was arrested in Hungary. He is accused of sending more than 15,000 Jews to their deaths at Auschwitz. But Hungarian police did not arrest the 97-year-old until a British newspaper, The Sun, made his location public. That has led some to say the authorities were dragging their feet. Most worryingly, those who complained have been the target of anti-Semitic hatred.
