我还是不明白。枪是可以自卫，但更是凶器。世界上总有一些不正常的人，用枪来杀害无辜的人。如果不允许持枪，可能也不会有那么多的枪击案了。

I still don't understand. Guns can be used in self-defense, but they are also lethal weapons. There are disturbed people throughout the world who could use guns to kill innocent people. If we don't allow them to have guns, then there won't be so many shootings.
