It's not the EU. The European Convention on Human rights is separate. It was drafted largely by British lawyers, under the auspices of Churchill, after WW2 - to try to stop anything quite so appalling happening again.
As for whole life tariffs, I'm not sure. Taking away any possibility of review, ever, may well create dangerous prisoners - because what have they got to lose if they murder a prison officer, for instance?
Some people are no doubt so dangerous that they should never be released - but shouldn't that danger be re-assessed? Someone may have been a continuing risk 10 years ago, can we assume he or she will always be a risk?
I have interviewed a released lifer - as in released from prison, but a life sentence does mean life in the sense that you can always be returned to prison if you breach the conditions of release.
He had reformed over a period of 20 years. It doesn't excuse his crime, but the circumstances that led up to it were appalling. He had no way of knowing how to fit into society because he had been cast out as a child, with neglectful/absent/actively cruel parenting followed by time in 'care' (he ran away) and life on the streets. (One parent had died, and who knows what the other parent would have been like if that tragedy hadn't affected them...)
What reformed him was a prison tutor who persuaded him to get an education, which in turn opened his eyes to the world. Education helped him to understand other people's rights and feelings and to understand rights and responsibilities.
Since being released, he has made a significant contribution to the world but he told me he knows that he can never put right what he did wrong. He just wants to justify the belief that tutor showed in him - he never wants to let her down.
It was quite moving but part of me was cynical, thinking 'has he just learned that these are the right things to say?' But I know for sure he has not re-offended. And he did serve 20 years.
