To be clear, gun accidents are not only limited to foot-shootings but to fatalities as well. One happened just last week here. A father shot his 7 year old in the chest in the parking lot of a gun store. While in high school one student was shot and killed by a friend with a gun.

I don't disagree with your argument but if you want to be honest about it you have to admit that there are a non-zero number of a accidental shootings that result in death, usually among family members.
