Gun violence defined literally means the use of a firearm to threaten or inflict violence or harm. Gun violence may be broadly defined as a category of violence and crime committed with the use of a firearm; it may or may not include actions ruled as self-defense, actions for law enforcement, or the safe lawful use of firearms for sport, hunting, and target practice. Gun violence encompasses intentional crime characterized as homicide (although not all homicide is automatically a crime) and assault with a deadly weapon, as well as unintentional injury and death resulting from the misuse of firearms, sometimes by children and adolescents. Gun violence statistics also may include self-inflicted gunshot wounds (both suicide, attempted suicide and suicide/homicide combinations sometimes seen within families).
