According to Uchida (2004), it was Eric Monkkonen - a scholar - who took
an entirely different approach in 1981 by using quantitative methods to explain the development of policing in 23 cities from 1860 to 1920. Uchida (2004) further states that it is Monkkonen who pointed out the origin of the concept crime prevention. In addition, these historical analyses revealed the challenges of corruption, brutality, and inefficiency in policing. The major emphasis of Monkkonen‘s (1992) work was to examine the development in policing since 900 A.D. and to determine whether the role of the police in America and all over the world has changed over a period of about 300 years.
