Khashoggi murder was a 'state killing,' says UN investigator

The brutal murder of journalist Jamal Khashoggi in Turkey's Saudi consulate last October changed Saudi Arabia’s global image and tainted its relationship with the U.S. Now, a United Nations panel has released a report detailing how Khashoggi was killed and who knew about it. Nick Schifrin talks to the report’s author, Agnes Callamard, about why the "premeditated" crime wasn't a rogue operation.
