I was unaware that Jeremy HAD mental health issues. Psychopathy is a personality disorder and the majority of psychopaths don't commit murder -although they are as capable of committing other crimes as any other convicted criminal- and would therefore not be regarded as "criminally insane" and not suitable for hospitalization in places such as Broadmoor and Ashworth.
You are unaware JB as mental health issues , as he probably does not , if he had , over a 30 year period involving nearly 30 prison moves , he would have passed through Ashworth or Broadmoor .
Category A prisoners , do get moved around , but 30 times is very unusual .
