It’s one day after another mass shooting in America – this time, at a private Christian elementary school in Nashville, Tennessee. It raises the same old, yet vital, unanswered questions? How long will this remain the norm? How long before legislators step in to actually save lives, as in so many other democratic nations? Firearms are the leading cause of death among American children and adolescents aged between one and 19 – and in Nashville, three children were among the six slaughtered at their school. Our first guest tonight is himself a survivor of gun violence: at 17, Joseph Sakran survived a bullet wound to the throat. Now he is a trauma surgeon in Baltimore, Maryland, regularly seeing at close quarters the visceral violence that these weapons cause. 

Also on today's show: Martin Indyk, former US Ambassador to Israel; former tennis star Boris Becker and Alex Gibney, director of "Boom! Boom! The World vs. Boris Becker”
