People are injured, sometimes fatally, when bullets discharged into the air fall back down. The mortality rate among those struck by falling bullets is about 32%, compared with about 2% to 6% normally associated with gunshot wounds.[5] The higher mortality is related to the higher incidence of head wounds from falling bullets.
A study by the U.S. Centers for Disease Control and Prevention (CDC) found that 80% of celebratory gunfire-related injuries are to the head, feet, and shoulders.[6] In the U.S. Commonwealth of Puerto Rico, about two people die and about 25 more are injured each year from celebratory gunfire on New Year's Eve, the CDC says.[3] Between the years 1985 and 1992, doctors at the King/Drew Medical Center in Los Angeles, California, treated some 118 people for random falling-bullet injuries. Thirty-eight of them died.[7] Kuwaitis celebrating in 1991 at the end of the Gulf War by firing weapons into the air caused 20 deaths from falling bullets.[7]
