Homicide refers to the act of killing another human being. There are many types of homicide, including criminal homicide, when a person purposely, knowingly, recklessly or negligently causes the death of another (i.e., murder and manslaughter), and there is non-criminal homicide in which the law allows homicide by allowing certain defences to criminal charges (i.e, self-defence). This book examines new developments in this field.
