美国拥有两项特殊的法律，一个是“不退让法”(Stand Your Ground Law)，一个是“城堡法”(Castle Doctrine)。
1、“不退让法”：允许个人在面对威胁时，无需退让，可以直接使用致命武力进行自卫，无论是在公共场所还是在私人场所。
2、“城堡法”：允许个人在自己的家中（或其他特定地点，如工作场所或车辆）面对入侵时使用致命武力进行自卫，无需尝试撤退。『太飒了！黑人半夜硬闯华人家庭，50岁妻子愤怒反杀，连开数枪直接击毙！』https://mp.weixin.qq.com/s?__biz=MjM5MTY0NTExMA==&mid=2654864088&idx=1&sn=fafc77d2004432daffabc25b2d53396f&chksm=bc0d7d3d83f912ff17141120903433aa2b850484c25f371012cd93052f1857b75ed3cbaf74f0&xtrack=1&scene=90&subscene=93&sessionid=1716051005&flutter_pos=0&clicktime=1716051010&enterid=1716051010&ascene=56&fasttmpl_type=0&fasttmpl_fullversion=7210647-zh_CN-zip&fasttmpl_flag=0&realreporttime=1716051010341&devicetype=android-31&version=2800313b&nettype=cmnet&lang=zh_CN&session_us=gh_0d2dd2e8f718&countrycode=CN&exportkey=n_ChQIAhIQKwNlaCpKBu1RlP1o6jBWyBLxAQIE97dBBAEAAAAAAJEJDp2e7tgAAAAOpnltbLcz9gKNyK89dVj0XfYjzGM1BWgIX4NX%2BSAxxrN9GIxgKUBkuHf3wU9F%2B5DuO%2BwMGi6TJ1zR83J%2FjIPKKg0q92Km2Hv4mdp5sAbn%2BTryLGU8XeOKhn7uAQBNo%2Br6hHthY4WfTU8l9nHALN1j6IUPU9Oy2S9tJDTe7rjcKMopdulo2KYKexHL%2B0MV7mZXNatnhRJYKUkTVCqwlIe%2Bh%2F6wkEl4dCiL%2FVDKKJe%2BaGnk8gHRTc0R3jx65x7hyzmQTPsVXgmo0zVaRb%2BPKloOXHgjDzedieX6zQ4%3D&pass_ticket=atv9Y%2B0ZqCCOcqgjQ1K5dLeWnKgSSf92giHBJUF%2B4ENCcQ%2Fgd3rAPl1fWZJ6AjfNJnlUn0NIBG5i3USFdX2Jqg%3D%3D&wx_header=3
