Final Report of the President’s Task Force on 21st Century Policing, May 2015.

“Law enforcement culture should embrace a guardian—rather than a warrior—mindset to build trust and legitimacy both within agencies and withthe public. Toward that end, law enforcement agencies should adopt procedural justice as the guiding principle for internal and external policies and practices to guide their interactions with rank and file officers and with the citizens they serve. Law enforcement agencies should also establish a culture of transparency and accountability to build public trust and legitimacy. This is critical to ensuring decision making is understood and in accord with stated policy.”
