(Life Sentence) , How Long?

A Life sentence should be what it say's on the tin. But in many county's this can mean as little as 10 years up to a full life sentence. In the last few months their have been a number of cases in the press in the UK that have given men a life sentence, but will he seve this time?. He could be up for parole after 10 years if he is a good boy, now how can this be right?. In the USA a life sentence does mean that, they have a life sentence with no posibility of parole. In the UK their are about 30 lifers. These men will never get out of prison. But I think these are men that have done such bad crimes that the public would never stand for these men to be released. I think this question will keep ranging for a long time.
