As a society, we are captivated by policing; we watch police procedurals and fly-on-the-wall documentaries and absorb the headlines on the rolling news. Yet how much do we really know about the world that policing inhabits and reveals? In his eye-opening new book, John Sutherland invites us to step behind the cordon tape and bear witness to the things that he has seen in his 25 years of service. Tackling ten of the biggest challenges facing society today - from alcohol abuse, drug addiction and domestic violence to knife crime, terrorism and sexual offences - we are introduced to people who have been pushed to the limits. In doing so, we gain a clearer sense of what needs to be done in order to make the cities we live in better places for us all to live. Deeply revealing, courageous and moving, this is a book that will change what you see when you walk down the street.
