Some homicides are not illegal. Criminal laws carve out exceptions for some killings which would otherwise fall under criminal laws against manslaughter or murder. These are referred to as “justified homicide”. One primary example is a killing in justified self-defense or defense of someone else. Such a homicide is deemed justified if the situation called for self-defense and state law allows lethal force in that type of situation. Most state laws allow justified homicide to defend oneself or another from credible threat of serious crimes such as rape, armed robbery and murder.
