Batman: The No-Gun Rule That Defines the Dark Knight

A thread on r/batman is circulating about Batman's long-standing refusal to use guns, one of his most iconic character traits. It's pretty basic Batman lore at this point—he watched his parents die and refuses to use firearms, making hand-to-hand combat and gadgets his signature moves. But the thread's probably gotten popular because it either just came up in a movie or show that broke the rule, or someone's defending it against fair criticism. The no-guns rule is core to what makes Batman Batman, even if it does create some narrative awkwardness sometimes.
