Policing is never a precise science: low arrest and conviction rates may indicate a force is doing its job in catching criminals badly or that it is doing its job of preventing crime brilliantly. It also requires difficult choices that may not win plaudits: a stern caution can, in some cases, do far more good than a rules-dictated prosecution.
