Yair Lapid - Leader, Yesh Atid Party, Israel

The latest paroxysm of violence between Israel and Palestine has conjured up a host of horrifying images. Israelis have been stabbed in random street attacks, while Palestinian suspects have been shot dead by Israeli police when seemingly no longer a threat, and an innocent bystander was beaten to death by an incensed Israeli crowd. Stephen Sackur speaks to Yair Lapid, former minister and leader of Israel's Yesh Atid party. He has called on Israelis to shoot to kill at the first sign of danger. Will that kind of language improve security?
