Now, For Your Daily Dose Of Perspective
Bear in mind this is a harbour city with a population of 2 million people.
For comparison: Monterrey, Mexico, a city half the size of Vancouver, just experienced a shootout between naval officers and "about a dozen suspected drug hitmen" outside a shopping centre. Well over 2,000 people have been killed in Mexico in drug-war related homicides.
Stockholm (which is around the same size as Vancouver) in violence-filled Sweden, had 60.
Even Seattle, a peaceful city about a third the size of Vancouver and only 150 kilometers away, had 29 homicides.
Canada had 605 total homicides last year. That's death caused by another person, not just murders; so drunken idiots getting stabbed by other drunken idiots outside a bar is in that count, too.
Not really enough to panic about just yet, I don't think.
