A banner's unfurled with the news. This Japanese court has ordered the retrial of Iwao Hakamada, who's believed to be the world's longest serving death row inmate. Hakamada is now 78. He was arrested in 1966 for the robbery and murder of a family. He initially admitted to the charges but pleaded not guilty in court. Supporters, led by his sister, say DNA tests now throw into doubt evidence of his guilt.
