The United Nations Development Programme has published an extensive report by Langer Research Associates on public attitudes toward the police in Afghanistan. The Police Perception Survey, commissioned by the UNDP Law and Order Trust Fund for Afghanistan, provides a detailed examination of public impressions of the Afghan National Police across a range of measures, include statistical modeling of the predictors of support for the police force and confidence in its abilities. Field work was carried out by the Afghan Center for Socio-economic and Opinion Research in Kabul, a subsidiary of D3 Systems in Vienna, Va. Langer Research Associates conducted an in-depth literature review on attitudes toward policing, consulted on the questionnaire design, analyzed the data and wrote the report. See it here.
