Three-quarters of all U.S. murders in 2017 – 14,542 out of 19,510 – involved a firearm. About half (51%) of all suicides that year – 23,854 out of 47,173 – involved a gun. So yes....
Moronic viewpoint. You cannot count suicides, because in countries without gun availability suicides continue- and would continue here if guns were gone. You also discount the number of times guns are used to protect against crime. Ethically, you can't deny a right to someone because of another's actions.
