What? A 25-year-old gunman wearing a black trench coat opened fire in the canteen at Dawson College, a school in downtown Montreal, Canada. When? Last Wednesday afternoon. Where? Where did he get the gun? Unlike Hong Kong, it is not illegal to own a gun in Canada. After a shooting spree at another Montreal college in 1989, the gun laws were tightened. Gun owners must register their weapons, but there are even plans to scrap that because people have complained it is expensive and bureaucratic. Who? Who was hurt? A young woman was killed and 19 others were injured, some critically. The police opened fire on the gunman, but it was a self-inflicted gunshot wound to the head that killed him. Why? Why did he do it? A few hours before he went on his killing spree, the gunman wrote in an online journal: 'School sucks, work sucks, life sucks. What else can I say?' How? How has the country reacted? The city of Montreal, known for its cafe culture and fun atmosphere, is in shock. The Prime Minister, Stephen Harper, called the shootings 'a cowardly and senseless act of violence'.
