What's it like to literally talk someone down from a ledge? How do you cope with being a witness to the most extreme examples of domestic violence, terrorism, and murder? John Sutherland explains... Having served on the frontlines of policing, from PC level, all the way to Chief Superintendent, John has seen the best and worst of society. He's been a negotiator, charged with communicating with the most venerable and the most violent in society. He's been the first on the scene when terror incidents take place, and he's seen the evolution of the drug trade and its new tactics. We discuss his new book, Crossing the Line: Lessons From a Life on Duty, and wow, there's a lot to chat about!   See acast.com/privacy for privacy and opt-out information.
