Gov. Roy Cooper signed a slate of policing reforms into law Thursday, creating a new duty for officers to intervene if they see another officer using excessive force. In addition, there’s new required training for officers. For example, new psychological exams for officers and a new requirement that the State Bureau of Investigation must investigate death at the hands of law enforcement when the governor, a law enforcement agency head, a district attorney or the commissioner of prisoners requests it.
