It's not an 'old chestnut' Lookout - it's estimated that around 25% of the prison population are psychopaths.
This is from 1998 -
"The Hare Psychopathy Checklist Revised (PCL-R) is becoming increasingly recognized as a valid and reliable method for assessing psychopathy in male forensic populations. Previous research has supported the view that the scale has good psythomeiric properties, however, most work to date has been conducted with North American samples. In the present study the PCL-R was administered to 104 inmates admitted to Grendon thereapeulic prison for long-term psychotherapy. Measures of internal consistency and inter-item reliability were in the range of acceptable to good. Factor analysis using oblique rotation identified two main factors which were similar to the two-factor model proposed by Hare. Factor congruence coefficients indicated that the factors extracted were almost identical to those obtained in North American samples. Twenty six percent of the sample were classified as psychopaths, which is close to the LeveLs reported in North American prison settings, but considerably higher than previous research involving UK samples. This is consistent with the selection criteria for Grendon which emphasize the presence of ‘personality disorder’ or ‘psychopathy’ as a prerequisite. Overall, the results can be viewed as offering further support to the growing literature attesting to the reliability and factor stnwture of the PCL-R."

"Opened in 1962, Grendon was initially used as an experimental psychiatric prison and psychiatric unit for prisoners with antisocial personality disorders. It developed into a therapeutic community (tc) prison based upon principles established at the Henderson Hospital in London. There are five, sometimes six discrete therapeutic communities, each with over 40 resident prisoners. In 2014, a small tc opened for prisoners with learning disabilities who had previously been excluded from treatment. This 'TC+' was modelled on similar projects begun the previous year at Dovegate and Gartree Prisons.
https://en.m.wikipedia.org/wiki/HM_Prison_GrendonHMP Wakefield is a high-security prison for men typically in security categories A and B.
HMP Wakefield was originally built as a house of correction in 1594. The current prison was designated a ‘dispersal' prison in 1966 (the longest of the remaining original group). It is now a main lifer centre with the focus on serious sex offenders. The average prison roll is approximately 740 including approximately 100 Category A and 10 High Risk Category A prisoners.
Wakefield houses a Close Supervision Centre (CSC) a small therapeutic centre aiming to provide a supportive, safe, structured and consistent environment for some of the most challenging offenders.
http://www.justice.gov.uk/contacts/prison-finder/wakefieldI wouldn't ignore the fact that Bamber remains in an A-Cat prison - I'd suggest it's relevant.. I'd go on to further suggest the prison authorities know much more about Bambers 'behaviours' than any of us do - hence why he remains a high risk prisoner.
* Off topic - I wasn't sure if Bamber was in Full Sutton or Wakefield so double checked on the OS. But it reminded me to warn others - as I didn't learn this until 2013 - stamps are used as currency the same as tabacco
