Life imprisonment around the world

Life imprisonment is any sentence of imprisonment for a crime under which convicted people are to remain in prison either for the rest of their natural lives or until pardoned, paroled or otherwise commuted to a fixed term. Crimes for which, in some countries, a person could receive this sentence include murder, attempted murder, conspiracy to commit murder, apostasy, terrorism, severe child abuse, rape, child rape, espionage, treason, high treason, drug dealing, drug trafficking, drug possession, human trafficking, severe cases of fraud, severe cases of financial crimes, aggravated criminal damage in English law, and aggravated cases of arson, kidnapping, burglary, or robbery which result in death or grievous bodily harm, piracy, aircraft hijacking, and in certain cases genocide, ethnic cleansing, crimes against humanity, certain war crimes or any three felonies in case of three-strikes law. Life imprisonment (as a maximum term) can also be imposed, in certain countries, for traffic offenses causing death. Life imprisonment is not used in all countries.

Where life imprisonment is a possible sentence, there may also exist formal mechanisms for requesting parole after a certain period of prison time. This means that a convict could be entitled to spend the rest of the sentence (until that individual dies) outside prison. Early release is usually conditional on past and future conduct, possibly with certain restrictions or obligations. In contrast, when a fixed term of imprisonment has ended, the convict is free. The length of time served and the conditions surrounding parole vary. Being eligible for parole does not necessarily ensure that parole will be granted. In some countries, parole does not exist but a life sentence may – after a successful application – be commuted to a fixed-term sentence, after which the offender is released as if the sentence served was that originally imposed.
