Losing your immunity

摘要

It was a sombre Stephen Harper who ad-dressed Canadians on October 22nd. A lone gunman had fatally shot a young soldier standing guard at the National War Memorial in the capital, Ottawa, and then entered Canada's parliament building where he was killed. The prime minister linked the shooting to the murder earlier in the week of another Canadian soldier. Both, he said, were a grim reminder that Canada is not immune to the type of terrorist attacks seen around the world.
