The Fifth Estate presents a comprehensive inquiry into this year's mass shooting in Nova Scotia, chronicling 13 hours of mayhem that constitute one of Canada's deadliest events. [Correction: In the video, we incorrectly said officers jumped out of a cruiser outside the Onslow fire hall and began firing. In fact, the person who was interviewed said it was not a cruiser and she believed it was a Hyundai. Nova Scotia's Serious Incident Response Team has since found that it was an unmarked police vehicle.]
