It was one of the first examples of scientific classification in law enforcement. A year later in 1830 Lambert Adolph a statistician from Belgium outlined the foundations for Bertillons work by putting forward his belief that no human bodies are exactly alike. Henceforth astounding research on fingerprints came about in 1823 when Professor John evangelist published his proposition which consisted of the discussion of 9 fingerprint patterns. Crime scene analysis combines the human factor with scientific procedures and methods to interpret what has occurred. The standard at the time was that if someone had specialized knowledge, and that knowledge seemed to be helpful to investigators, then the court would allow the testimony, says Jonathan Koehler, a behavioral scientist and law professor at Northwestern University. The reforms went a long way to rid policing of corruption and patronage, but they also wanted police entrusted with more paternalistic responsibilities basically, to enforce virtue on immigrant populations whom progressive leaders thoughtlacked morality, discipline and industriousness.
