communities and local law enforcement, they're a composite of that local community. >> reporter: could go in dramatically different directions. beginning in the 1700s in the province of carolina and spreading throughout the south, slave patrols were created to create rebellions and enslave people from escaping. the first city police departments were formed in the mid 19th century, boston first, then new york. in many cases to deal with public drunkenness and social disorder. but the police often became tools of corruption for local politicians. efforts at reform in the 20th century gave departments more autonomy but led to policing tactics like stop and frisk,s with minorities in particular, leading to violent confrontations, the results of which we still see today.
