Trudeau pushes for safer skies after Iran plane downing

Prime Minister Justin Trudeau is ending eight days overseas Friday with a final stop at the Munich Security Conference. He says multilateral organizations are the best way to solve the world's biggest problems but they have to adapt to make sure all people get the benefit. He says he wants to work with other countries to implement rules for safer skies so nobody else gets on an airplane worrying that it's going to be shot down.
