There are many imprisoned men in the UK who have committed the same sort of atrocious sexual murders and woundings. The nature of the torture they have inflicted, using weapons and implements, is so horrendous that you wouldn't describe it to another person. These crimes are committed after death, too. Once you know, you can't unknow. If these offenders can be kept in prison for life in the UK, I believe we shouldn't call for the death sentence in another country. The parents and relatives of those women who are sexually tortured in this country have no public outcry to support their need for vengeance - these unimaginable offences have been dealt with by our justice system and many of these offenders are now in the 3 special hospitals - Rampton, Ashworth and Broadmoor - or the regional secure units, NHS forensic services.
The dilemma of feeling murderous ourselves, as a reaction to these abhorrent crimes, is what the people who have to control, treat and care for these offenders feel, too. They have to take an objective stance in order to learn more about such criminal behaviour, treat and re-assess their dangerousness, and report to the home secretary and regular tribunals in order to keep the public safe. It would be rare for someone who has sexually tortured and/or murdered to be released when their crimes have been so horrendous.
