Copperfield's excellent first book was vulnerable to criticism that it was just one man's experience, not representative etc etc. Notoriously, Tony McNulty MP dismissed it in the Commons as fiction.
The points Copperfield makes are too important to allow them to be so easily sidestepped, so this book is the testimony of some dozens of anonymous serving officers. As Copperfield's true identity was eventually established, they are all taking a real risk and must feel strongly about these issues.
To start there are a couple of chapters about the perennial problems of police work, dealing with society's human vermin and dealing with death, but the bulk of the book is about problems caused by politicians, courts and police senior management, i.e. new and often wholly unnecessary problems.
Criminals use extreme violence, especially against the police, at the drop of a hat, but are let off or charged with minor offences time and time again. Meanwhile the police are held to almost impossibly high standards. Like the army, they are often ill-equipped. They are still required to be PC Dixon when the world of Dock Green has long passed.
The big issue, though, as with the previous book, is the colossal amount of time and manpower that is simply wasted. Vast numbers of nominal policemen never set foot in the mean streets, but confine themselves to sending e-mails about targets from the comfort of their offices. For those doing real police work, procedures are wildly cumbersome, and they must take ten times as much time for diversity and sensitivity courses as for courses on catching criminals.
If the Home Secretary hasn't read this book she certainly should.
