Unemployed older men became night watchmen. These night 
     watchmen caught criminals and if they required help, 
     they could use greggers or noisemaking rattles to signal 
     parish constables.

     In addition, private "thief-takers" could be hired by 
     victims of crime to apprehend criminals.

     In 1748, Chief Magistrate Henry Fielding founded the 
     Bow Street Runners ("runner" being a synonym for "thief-taker"). 
     The Bow Street Runners wore a blue dress
     coat with brass buttons and a red waistcoat, which caused
     them to be referred to as the "Robin Redbreasts".
     The Bow Street Runners were something between barristers and 
     thief-takers.

     In 1752, Henry Fielding used his own publication, "The Covent
     Garden Journal", to invite victims of crime to contact him
     with details of the crimes committed against them, including
     properties stolen. Advertisements were then placed in the journal
     for the recovery of these items, usually with a reward
     attached for finding the perpetrator or the property. The
     success of these advertisements encouraged others to publish 
     journals dedicated to describing criminals and offenses, beginning
     with a publication by Henry Fielding's half-brother John, 
     "The Public Advertiser". The Public Advertiser eventually 
     became a weekly journal called "The Public Hue and Cry";
     later "The Police Gazette."

     In 1754, Henry Fielding was replaced by his half-brother, 
     John Fielding.

     On September 29, 1829, Robert Peel, 2nd
     Baronet created the Metropolitan Police.

    Police magistrates were able to try "minor offenses" — vagrancy, 
    drunkenness, minor larceny and prostitution — without a jury and 
    sentence the guilty to hard labor. Thus, they created a way to bypass any
    checks on the justice system. Police magistrate Alan Laing of 52-3 Hatton 
    Street, was Charles Dickens' model for the police magistrate "Mr. Fang of 
    Mutton Hill" in "Oliver Twist". Dickens wrote that he "sought a
    magistrate whose harshness and insolence would render him a fit
    subject ..." 
    
     ("Oliver Twist" Penguin ed., 2002, p. 498) 
    
    and found Mr. Laing an appropriate figure.
