禁止持有武器的法律。只会解除那些本来就不打算或没有决心要犯罪的人的武装……这样的法律只会让受害者变得更糟，让行凶者更强；它们相当于鼓励而不是阻止凶杀，因为一个没有武装的人更可能被一个武装的人袭击。
The laws that forbid the carrying of arms are laws of such a nature. They disarm only those who are neither inclined nor determined to commit crimes.... Such laws make things worse for the assaulted and better for the assailants; they serve rather to encourage than to prevent homicides, for an unarmed man may be attacked with greater confidence than an armed man.

不以法推行法度，则国事没有常规，办事的时候就没有规矩可循；法度不用法的手段推行，则政令不能贯彻。
