Having a Father's Day

In 2009, Boko Haram, a small Islamist group, launched an insurgency in the north eastern Nigerian city of Maiduguri. The conflict would eventually force hundreds of thousands from their homes, and leave tens of thousands dead. We hear a witness account of how the violence started. Plus, this past week Americans have been observing the Martin Luther King Jr. Day national holiday. The long campaign to have Dr King formally recognized in the US was led by his widow, Coretta Scott King. We hear from her daughter, Dr Bernice King, about the campaign. We dip into the BBC archive to bring you the story of the notorious Stanford Prison Experiment. Also, from the 1980s, a time when many wanted to get out of East Germany and into the West, the young woman who decided to go the other way and set up a new life in the East. And the Dutchman behind the first bike sharing scheme.
