Each of Britain's fifty-two police forces is responsible for law enforcement in its own area. In addition there are various national and regional connections (for example, in areas of training or the transfer of criminal records), and local forces cooperate with each other.
Some special services, such as the Fraud Squad (who investigate financial crimes), are available to any local force in England and Wales. In general, however, the local police forces work independently under their own Chief Constables. Each force is maintained by a local police authority. The exception is London, where the Metropolitan Police are responsible to the Home Secretary.
Police duties cover a wide range of activities, from traffic control to more specialised departments such as river police. Each independent force has a uniformed branch and a Criminal Investigation Department (C1D) with detectives in plain clothes. In addition the police authorities in England and Wales employ 40,000 civilians and nearly 5,000 traffic wardens.
Britain has relatively few police – approximately one policeman for every 400 people – and traditionally they are armed only with truncheons except in special circumstances.
However, recent years have seen some major changes in police policy in respond to industrial disputes and inner city violence in Great Britain. The situation in Northern Ireland, where the Royal Ulster Constabulary are the local police force, has also meant a change in the style of maintaining law and order. In general, there has been an increase in the number of special units trained in crowd and riot control and in the use of firearms, a controversial area for the British police. The number of police has risen along with the crime rate.
