Can you shoot when America is robbed, Zhihu?

Although guns can be legally owned in the United States, they can only be kept at home for self-defense. When a private house is illegally invaded, you can shoot to stop the invasion, but you can't go out with a gun, or you will be killed by the police. From the news, no ordinary American dares to walk in the street or drive with a gun, and no one dares to carry a gun in demonstrations and riots in the United States. So Americans can shoot back when they are robbed at home, but they can't shoot themselves when they are robbed outside.
