The gunman masqueraded as a policeman.

On Saturday, a gunman that masqueraded as a policeman killed 16 people in Canada in a shootout that lasted 12 hours. He wore a police uniform and had also gone to the effort of disguising his car as a police cruiser. This is the worst mass killing in Canada’s modern history. The police are not yet sure if the shooting is related to terrorism. There seems to be no connection between the gunman and his victims.
