Killer Instinct

Forensic psychiatrist Donald Grant asks what it is about murder that fascinates us. Is it a chill whisper of fear reminding us we too can kill? Grant describes ten true murder cases, each different, each complex, each with unique triggers. He argues that our restless chatter about it, our state of heightened alert, our endless viewing, may be play therapy, reassuring us that our own killer instinct is under control.
