A murderer has a first-class-honour degree in psychology according to Tonge et al. (2012) at 27:46. He has also been a criminology PhD student after he had been convicted of 2 crimes. He is called Stephen Shaun Griffiths.
Stephen Shaun Griffiths had been diagnosed with a personality disorder in particular with violent fantasies and had attempted to steal from a shop before he has murdered 3 drug-addict prostitutes in Bradford. (Cf. a murderer who had been arrested in the U.K. because he stole underwear from a shop. That thief was not convicted of theft, and he has murdered after a U.K. authority had liberated him because it fails to convict him.) Cf. a report by Professor of Criminology at Birmingham City University David Wilson in Tonge et al. (2012) shortly after 34:33. He had psychiatric treatment before these murderers says a narrator in Tonge et al. (2012) shortly after 35:17.
Cf. neuroscientists who did not stop Neuroscience PhD Student James Eagan Holmes from murders.
