Unlawful killing in the context of "Law of the Republic of Ireland"

Murder is the unlawful killing of another human without justification or valid excuse committed with the necessary intention as defined by the law in a specific jurisdiction. This state of mind may, depending upon the jurisdiction, distinguish murder from other forms of unlawful homicide, such as manslaughter. Manslaughter is killing committed in the absence of malice, such as in the case of voluntary manslaughter brought about by reasonable provocation, or diminished capacity. Involuntary manslaughter, where it is recognized, is a killing that lacks all but the most attenuated guilty intent, recklessness.

Most societies consider murder to be an extremely serious crime, and thus believe that a person convicted of murder should receive harsh punishments for the purposes of retribution, deterrence, rehabilitation, or incapacitation. In most countries, a person convicted of murder generally receives a long-term prison sentence, a life sentence, or capital punishment. Some countries, states, and territories, including the United Kingdom and other countries with English-derived common law, mandate life imprisonment for murder, whether it is subdivided into first-degree murder or otherwise.

Operation Paget was the British Metropolitan Police inquiry established in 2004 to investigate the conspiracy theories about the death of Diana, Princess of Wales, in a car crash in Paris in 1997. The inquiry's first report with the findings of the criminal investigation was published in 2006. The inquiry was wound up following the conclusion of the British inquest in 2008, in which a jury delivered its verdict of an "unlawful killing" due to the "gross negligence" of both the driver of Diana's car and the pursuing paparazzi.
