如果一个火星人正在观看我们的电视节目，他会得出结论：枪比锤子更常见。它们本身并不是邪恶的——它们只是工具——但无论你走到哪里，坏人都有它们。正义之人至少应该知道它们是如何运作的。
(If a Martian were watching our television shows, he'd conclude that guns were more common than hammers. They're not evil themselves--they're tools--but everywhere you go, bad people have them. It behooves the righteous to at least know how they work.)
