A knifeman* kills eight children and wounds five more in a brutal attack at a school in China. H/T to War On Guns.
People bent on committing violence will do so with whatever tools are available.
Of my five friends who have been murdered, not one was killed by gunshot. A sixth friend was shot in a public parking lot, in broad daylight. He survived. The FBI Uniform Crime Reports list knives or cutting instruments, blunt objects, hands-fists-feet-etc., poison, explosives, fire, narcotics, drowning, strangulation, asphyxiation, and "other or weapon not stated" as facilitators of homicide. Banning guns in other countries might superficially or temporarily reduce crimes committed with firearms, but overall violence increases when criminals know victims are helpless.
And that includes criminal governments.
* News writers are fond of calling criminals who use guns "gunmen." So why don't they prepend other criminals' weapons of choice?
