Justifiable homicide—Certain willful killings must be reported as justifiable or excusable. In the UCR Program, justifiable homicide is defined as and limited to:
- The killing of a felon by a peace officer in the line of duty.
- The killing of a felon, during the commission of a felony, by a private citizen.
Because these killings are determined through law enforcement investigation to be justifiable, they are tabulated separately from murder and nonnegligent manslaughter.
