I admit to being a little prejudiced as I am a volunteer Chaplain to the police and hence have some sympathy for the way they are often meligned and unfairly so. Although this book is dealing with history, it makes facinating watching to see how very much the force has changed though some of the problems remain consistent. Sadly the DVD ends in 1984 and much has changed since - so, when is an update due please ? I suppose a side interest is watching the old vehicles, buses, vans, cars and " Cop cars" with bells!
