Zofia Cisowski (L) leaves the morning testimony of the Braidwood Inquiry in Vancouver, British Columbia September 22, 2009. The inquiry stems from the death of her son, Polish immigrant Robert Dziekanski, in an incident in which he was shocked with a Taser stun gun several times in a confrontation with Royal Canadian Mounted Police officers at Vancouver International Airport in 2007. The exact cause of his death has never been determined.
