New York City police officers fire their weapons far less often than they did a decade ago, a statistic that has dropped along with the crime rate. But when they do fire, even at an armed suspect, there is often no one returning fire at the officers. Officers hit their targets roughly 34 percent of the time.

When they fire at dogs, roughly 55 percent of shots hit home. Most of their targets are pit bulls, with a smattering of Rottweilers and German shepherds.

Officers’ guns go off unintentionally or by accident for a variety of reasons: wrestling with suspects, cleaning the weapons, leaning on holsters  even once, in 1996, when a gun was put in an oven for safekeeping.

While the drop in police shootings was already clear, the details were among the myriad facts included in 11 years’ worth of annual New York Police Department firearms-discharge reports that were, without fanfare, handed over to the City Council this week and earlier to the New York Civil Liberties Union.
