Thanks for this, Zank! That video was really chilling! During the early 60's I was a Psyche Nurse at Riverview Psychiatric Hospital in B.C. During my six years there, I talked to a couple of serial killers and the one thing that really stood out was the dispassionate way they talked about their crimes! BTW: I recall a TV interview with a psychiatrist who studied serial killers. He found that most of them have five red flags in their background when they were young: 1.constantly lied to their parents 2 lit many small fires 3. were bed wetters 4.stole money and small objects 5, extreme cruelty to small animals such as kittens, puppies, and pet rabbits etc.!!
