Majorities of both black and white Americans say black people are treated less fairly than whites in dealing with the police and by the criminal justice system as a whole. In a
2019 Center survey, 84% of black adults said that, in dealing with police, blacks are generally treated less fairly than whites; 63% of whites said the same. Similarly, 87% of blacks and 61% of whites said the U.S. criminal justice system treats black people less fairly
Black adults are about five times as likely as whites to say they’ve been unfairly stopped by police because of their race or ethnicity (44% vs. 9%), according to the same survey. Black men are
especially likely to say this: 59% say they’ve been unfairly stopped, versus 31% of black women.
Black Americans are far less likely than whites to give police high marks for the
way they do their jobs. In a 2016 survey, only about a third of black adults said that police in their community did an “excellent” or “good” job in using the right amount of force (33%, compared with 75% of whites), treating racial and ethnic groups equally (35% vs. 75%), and holding officers accountable for misconduct (31% vs. 70%).
White police officers and their black colleagues have starkly different views on fundamental questions regarding the situation of blacks in American society, the 2016 survey found. For example, nearly all white officers (92%) – but only 29% of their black colleagues – said the U.S. had made the changes needed
to assure equal rights for blacks.
