How Crazy is Canada?

Alek Minassian did not commit suicide after running over and killing 10 and injuring 14 innocent bystanders in Toronto, Canada this past year. But he did his best to get shot and killed by a policeman who had his gun drawn, but who managed to take Minassian down without a shot being fired. What is the risk to you of someone like Minassian driving a car at you as you try to walk down the street?
