"Homicide" isn't necessarily murder. It also includes justifiable homicide, or self-defense.
But in this case, that isn't what is inflating it: it's the inclusion of "suicide" in the count, although they don't explicitly say so.
Suicide rates are driven by culture. If you restrict one means of suicide, other means increase to compensate. That's exactly what happened in Canada.
“But in this case, that isn’t what is inflating it: it’s the inclusion of “suicide” in the count, although they don’t explicitly say so.”
That’s teh bogusness. The real murder rate is 4.8 not 10.
