The British police
officer is a well-known figure to anyone who has visited Britain or who
has seen British films. Policemen are to be seen in towns and cities
keeping law and order, either walking in pairs down the streets
("walking the beat") or driving specially marked police cars. Once known
as 'panda cars' because of their distinctive markings, these are now
often jokingly referred to as 'jam sandwiches' because of the pink -
fluorescent stripe running horizontally around the bodywork. In the
past, policemen were often known as 'bobbies' after Sir Robert Peel, the
founder of the police force. Nowadays, common nicknames include 'the
cops', the fuzz', 'the pigs', and 'the Old Bill' (particularly in
London). Few people realise, however, that the police in Britain are
organised very differently from many other countries.
Most countries, for example, have a national police force which is
control1ed by central Government. Britain has no national police force,
although police policy is, governed by the central Government's Home
Office. Instead, there is a separate police force for each of 52 areas
into which the country is divided. Each has a police authority - a
committee of local county councillors and magistrates.
The forces co-operate with each other, but it is unusual for members .
of one force to operate in another's area unless they are asked to give
assistance. This sometimes happens when there has been a very serious
crime. A Chief Constable (the most senior police officer of a force) may
sometimes ask for the assistance of London's police force, based at New
Scotland Yard - known simply as "the Yard".

In most countries the police carry guns. In Britain, however, this is
extremely unusual. Policemen do not, as a rule, carry firearms in their
day¬-to-day work, though certain specialist units are trained to do so
and can be called upon to help the regular police force in situations
where firearms are involved, e.g. terrorist incidents, armed robberies,
etc. The only policemen who routinely carry weapons are those assigned
to guard politicians and diplomats, or special officers who patrol
airports.
In certain circumstances specially trained police officers can be armed,
but only with the signed permission of a magistrate.
All members of the police must have gained a certain level of academic
qualifications at school and undergone a period of intensive training.
Like in the army, there are a number of ranks: after the Chief Constable
comes the Assistant Chief Constable, Chief Superintendent, Chief
Inspector, Inspector, Sergeant and Constable. Women make up about 10 per
cent of the police force. The police are helped by a number of Special
Constables¬-members of the public who work for the police voluntarily
for a few hours a week.
Each police force has its own Criminal Investigation Department: (CID).
Members of CIDs are detectives, and they do not wear uniforms The other
uniformed people you see in British towns are traffic warden~ Their job
is to make sure that drivers obey the parking regulations. The~ have no
other powers - it is the police who are responsible for controlling
offences like speeding, careless driving and drunken driving
The duties of the police are varied, ranging from assisting at accidents
to safeguarding public order and dealing with lost property. One of
their main functions is, of course, apprehending criminals and would-be
¬criminals
