[T]he research on actual gunfights, the kind that happen not in a politician’s head but in fluorescent-lit stairwells and strip-mall restaurants around America, reveals something surprising.

In the New York City police department, for example, officers involved in gunfights typically hit their intended targets only 18% of the time, according to a Rand study. When they fired 16 times at an armed man outside the Empire State Building last summer, they hit nine bystanders and left 10 bullet holes in the suspect—a better-than-average hit ratio.
