According to the FBI's statistics, of the USA's approximately 15-16,000 homicides per year, 67% are committed with a firearm.
Of America's approximately 32,000 suicides each year, 80% are men of whom 60% use a firearm and 20% are women of whom 30% use a firearm.
There are also some accidental deaths due to firearms each year as well as a a number of killings in self-defense.
The figure is roughly 30,000 - what is misleading is not the number in the editorial but the description of the circumstances.
The second-best lie is the truth, twisted.
