Public Trust and Law Enforcement-- A Discussion for Policymakers [Updated December 13, 2018] [open pdf - 1MB]
"Several high-profile incidents where the police have apparently used excessive force against citizens have generated interest in what role Congress could play in facilitating efforts to build trust between the police and the people they serve. This report provides a brief overview of the federal government's role in police-community relations. Public confidence in the police declined in 2014 and 2015 after several high-profile incidents in which men of color were killed during confrontations with the police. Confidence in the police has rebounded in recent years and is now back to the historical average. However, certain groups, such as Hispanics, blacks, people under the age of 35, and individuals with liberal political leanings say they have less confidence in the police than whites, people over the age of 35, and people with conservative political leanings."
