"Peeky-Lou" and how Forensic Psychologists can be Manipulated and Fooled Outright.

 This is a link to a blogpost which raises the question of how well psychological "offender profiling" works when a killer has (or uses) multiple fantasy personas and kills different victims as different personas.

Medawar knows who the blog author means and has experience of him blitzing blogs and forums with multiple comments as different people. His real self has useful political connections and these, and the multiplicity of personas that he uses, are very good at putting investigators off the scent. So there is an element of cold calculation behind the multiple personas and it's not exactly the same sort of mental disorder that it looks like at first: it's a deeply psychopathic but highly-educated mind using disorders that he has studied during his medical training and practice to advance a hobby of tormenting and periodically killing people.

The mind in question failed his psychiatric screening tests at medical school, but was allowed to sit them a second time, where he passed with flying colours with the benefit of appropriate study and paid-for coaching by former law enforcement officers with appropriate training. This is another way in which forensic psychologists can be duped: by offenders prepared to sit up late with the texts used to train forensic psychologists and, indeed, retired forensic psychologists with financial needs.
