I have always been intrigued by the pre trial psychiatrist who was inducted by the defence to assess Jeremy Bamber.
In one of the books it says the psychiatrist told the defence " if ever there was a psychopath his name is Jeremy Bamber"
Having met Jeremy years ago and having spent time in his company, and having met people who may " fit that type of view " loosely speaking. All I can say there was nothing about Jeremy Bamber that made me think " this guys a weirdo" a bit overbearing and assertive and confident, but no red flags.
Also Jeremy to this day is always giving the impression of " im just a normal bloke who is wronged" officially at least he comes across in his blogs interviews, people who see him to this day as a " normal bloke "
Back in 1986 when the psychiatrist did the interview, he was completley protesting his innocence, none of his friends describe him as being abnormal in any shape or form so I am interested in what behaviour he showed for the psychiatrist to come to that conclusion. You would think given his circumstances he would play the " im innocent and a normal bloke " spiel, even if he was guilty. Especially as such a positive report would go in his favour.
He told Julie you could convince anyone of anything if you put your mind to it. He'd planned the massacre for over a year, he'd divulged his diablerie to Julie, he'd attempted to curry favour with Ann Eaton for months pre-murders, as he knew she wouldn't accept his version of events.
In the passage to which you refer (Chapter 26 of
Blood Relations) the psychiatrist says Bamber convinced himself he was innocent of the crime, maybe because he saw himself as his sister's accomplice (that's my opinion), and with the passage of time the awfulness of what he had done he had blocked out his mind, then forgotten it all.
I don't know what psychiatric phenomenon the professional had in mind, but it's not a bad analysis.
