Can lollipops reduce anti-social behaviour? Or wizards halt street gambling? Do fake bus stops protect pensioners? Will organising a dog show stop young people killing each other? Stevyn Colgan believes that the answer to all of those questions is 'Yes'. Packed with fascinating anecdotes and important questions, this astonishing book reveals the innovative and imaginative ways Colgan tried to prevent crime during his thirty years on the police force. Colgan worked for twelve of those years as part of a unique team called The Problem Solving Unit. With no budget and laughable resources, they were given an extraordinary brief - to solve problems of crime and disorder that wouldn't respond to traditional policing. They were told they could try anything as long as it wasn't illegal, wasn't immoral, wouldn't bring the police into disrepute, and didn't cost very much. With amusing, insightful and sometimes controversial approaches to problem solving, Colgan mixes personal anecdotes from his time on the force with real-world examples of how The Problem Solving Unit helped build communities and prevent recurring crime. At its core, this book's message is simple: police should direct far more effort towards preventing crime before it happens rather than solving crime after it has happened.
