HISTORICAL FEATURES IN CRIMINAL INVESTIGATION
The art and science of Criminal Investigation that exist today is the result of countless development since
policing was conceived and then institutionalized. The following is just a brief account of some of the major milestone in
the history of Criminal Investigation.
WORLDWIDE DEVELOPMENT
1720s, ENGLAND: - JONATHAN WILD He was a buckle maker then a brothel operator; a master criminal who
became Londons most effective criminal investigator. He was the most famous THIEF-CATCHER in 1720s. His
methods or techniques made popular the logic of EMPLOYING A THIEF TO CATCH A THIEF. He conceived the idea
of charging a fee for locating and returning stolen property to its rightful owners.
1750s, ENGLAND: - HENRY FIELDING An Englishman who wrote a novel entitled Tom Jones and was appointed
as magistrate (sheriff) for the areas of Westminster and Middle Age, London. He was the creator of the BOW STREET
RUNNERS while he was the magistrate; he formed a group of police officers attached to the Bow Street Court, and not
in uniform, performing criminal investigative functions.
1753, ENGLAND: - SIR JOHN FIELDING The younger brother of Henry Fielding who took over the control of Bow
Street Court in 1753. His investigators were then called Bow Street Runners and became quite effective because of his
personal guidance despite the fact that he was blind. He introduced the practice of developing paid informants, printing
wanted notices, employing criminal raids, and bearing firearms and handcuffs.
1759, USA: The US CONGRESS created the office of the GENERAL AND REVENUE CUTTER SERVICE. This is the
first organized federal law enforcement and investigative effort made by the US government.
1800, LONDON: - PATRICK COLQUHOUN A prominent London president who proposed the unique idea of creating
sizeable uniformed force to police the city of London in order to remedy the public outcry concerning the alarming
increase of criminality during the early 1800s. His proposal was considered too radical and was dismissed by the Royal
Court.
1811, FRANCE: - EUGENE Francois VIDOCQ He was a criminal who turned Paris Investigator. He is a former
convict who became a notorious thief-catcher in France. He is credited as the founder of LA SURETE, France s
national detective organization. He made popular the concept of SET A THIEF TO CATCH A THIEF . He introduced
the concept of TRADE PROTECTION SOCIETY, which is a forerunner of our present-day credit card system. For
a fee, any owner of a shop or business establishment could obtain particulars concerning the financial solvency of new
customers. He created a squad of ex-convicts to aid the Paris police in crime investigation.
1829, LONDON: - SIR ROBERT PEELS The founder and chief organizer of the London Metropolitan Police the
SCOTLAND YARD. He reiterated the idea of creating sizeable police force in his recommendations, which lead to the
passage of the Metropolitan Police Act. This act had a tremendous impact on the history of criminal justice in general,
and on the development of criminal investigation specifically. He introduced the techniques of detecting crimes such
as: detectives concealing themselves, and secretly photographing and recording conversations.
1833, ENGLAND: The Scotland Yard employed the first undercover officer while in
USA: First daytime paid police department was established in Philadelphia, USA.
