[JURIST] Canada honored four slain RCMP officers Thursday afternoon in a nationally-televised memorial service [RCMP memorial website] attended by Prime Minister Paul Martin, Governor-General Adrienne Clarkson representing the Queen, and 10,000 police officers from Canada, the United States and around the world. Waves of Mounties in their red serge ceremonial uniforms marched through the streets of Edmonton to a huge sports pavilion at the University of Alberta where famous and ordinary Canadians joined to mourn the loss not just of members of a police force, but bearers of a national tradition going back to the nineteenth century and the settlement of the Canadian west. The four officers [RCMP profiles] – Peter Schiemann, 25, Leo Johnston, 32, Anthony Gordon, 28, and Brock Myrol, 29 – were killed last Thursday [JURIST report] in an ambush during a raid on a marijuana growing operation. The gunman committed suicide at the scene. The killings were the greatest loss of life suffered by the elite Canadian police in a single incident since 1885. CBC News has more. CTV News provides a video report on the service.
