Overview: Harlan County, Ky., has a history of violence and corruption associated with coal mining, but because that industry in Appalachia is a shell of its former self, law enforcement is dedicating its resources elsewhere. The county has been hit hard by a new kind of crime -- prescription drug dealing -- and it's up to Sheriff Marvin J. Lipfird to get it under control. In the reality-documentary series "Kentucky Justice," Lipfird and his team of deputies target everyone from street-corner dealers to city officials in a quest to clean up communities.
