Henry Fielding operated his own monied police, referred to as _________, which attempt to clean up earlier policing efforts by deciding which cases to investigate and which streets to protect.

Henry Fielding is well-known for establishing the Bow Street Runners, which are recognized as one of the first organized police forces in London during the 18th century. This group of "runners" aimed to improve law enforcement by specifically choosing which cases to pursue and which areas to patrol, addressing the inadequacies of prior policing methods. The Bow Street Runners were instrumental in creating a more organized approach to policing, emphasizing the need for a proactive and structured response to crime, which influenced the development of modern policing systems.

The other options do not accurately describe Henry Fielding's police initiative. Justices of the peace were judicial officers responsible for minor legal issues but did not operate a policing agency. "Friends or Foes" does not correlate with any established police force or initiative from that period. The Metropolitan Police was established later, in 1829, so it cannot be associated with Fielding's efforts in the earlier 18th century.
