life without possibility of parole

life without possibility of parole n. a sentence sometimes given for particularly vicious criminals in murder cases or to repeat felons, particularly if the crime is committed in a state which has no death penalty, the jury chooses not to impose the death penalty, or the judge feels it is simpler to lock the prisoner up and "throw away the key" rather than invite years of appeals while the prisoner languishes on death row. Opponents of capital punishment often advocate this penalty as a substitute for execution. It guarantees the criminal will not endanger the public, and the prospect of never being outside prison is severe punishment. Contrary arguments are that this penalty does not deter murderers, there is always the possibility of escape or killing a guard or fellow prisoner, or some soft-hearted Governor may someday reduce the sentence.
