Are you limiting the discussion to gun carry? I ask because an important consideration is having a gun ready for use at home, or at camp, or wherever you are stationed at the moment.

Yes, I know a person who benefited from their gun's presence. My folks live in a secluded area where strange things have happened and where the police arrival time is not anytime soon. I won't go into detail about how the person used their gun, but your imagination and common sense should be just as good.

Another thing to consider is that people tend to assume the gun user is healthy and strong. However, it's more appropriate to assume the gun user is relatively weak.

For example, it's more appropriate to assume a gun user is elderly, sick, injured, handicapped, or skinny/frail. If you're empathetic, you should be able to imagine many likely uses for a firearm. Would this relatively weak person benefit from carrying proper protection that would improve the odds in a fight? Should a grandma in a wheelchair be enabled to defend herself against robbers? Or should she just beg for them to spare her life? Or should we assume that she won't get robbed if she locks her doors and turns on the alarm? If grandma has use for a gun and others do not, then where exactly is that line? Can that line be clearly articulated in a law?
