i believe every us citizen who doesnt have a history of being violent, should be allowed to own, carry, and use a gun, anywhere in the united states where is not prohibited by the owner of that property. I think a school, airline, park, building, monument, etc should be allowed to decide if they want to allow or prohibit guns on thier property, instead of the government telling them "no you cant have a gun on a plane". People could ONLY use thier gun in self defense and hunting non-human animals that are not endangered, pets, etc. If they shoot someone, they will be charged with murder and will never be allowed to own a gun in the united states again. People might say this would increase murders, but say for some horrible reason you wanted to shoot someone, if you knew they were allowed to have a gun on them and use it if they were threatened by a gun they could use it in defense, wouldnt you be a little more hesitant?
