There are 5 defined eras of law enforcement.  This is the
first of the five (5) eras.  We will take a look back at the
evolution of law enforcement and how our current day law
enforcement has been influenced by hundreds of thousands of years
of people trying to control crime, offenses and human behavior not
acceptable in their communities.  Early history set a template
for how our modern day law enforcement functions. We use many
of the terms, titles and ideas that were developed long
before America was even a nation.
