I listed Suicide, Homicide, Killed by police, and Killed in self-defense. That pretty well covers all categories. Homicide, as I used it in the post, was intended to cover unlawful homicide, ie: manslaughter and murder.

Restrictions on law-abiding gun owners has no effect on criminals. Why do you think taking my guns away from me will somehow make a criminal give his up?

Yes, if guns had never been invented there would be no gun deaths. So you would be happier is more people were stabbed or beaten to death? Guns do save lives, lots of them. My own wife is alive because she had a gun to protect herself when she needed it. Otherwise she would have been murdered. Would that have made you happy?

Only about 20% of gun owners are hunters. The rest of us use guns for other, lawful, reasons. Staying proficient in anything takes practice. Practice with a gun means ammo used.
