Both departments stopped black people at a rate more than 2x higher than white people and were more likely to search, arrest, and use force against black people during a stop. Both departments not only use force more often but also use more severe forms of force against black people than other groups, even after controlling for arrest rates and alleged level of resistance.We also found evidence of anti-Latinx bias, anti-LGBT bias and bias against people with disabilities in both departments' search practices

Examining the Role of Use of Force Policies in Ending Police Violence

Then we reviewed the use of force guidelines of the nation’s largest police departments to determine where these policies were currently in place and whether they were associated with fewer police-involved killings. We found all of the policies to predict lower rates of police-involved killings, with substantially fewer police-involved killings among departments that have more of these policies in place. These results suggest specific changes to police department use of force policies can significantly reduce police violence in America.
The Significance of Mixed-Race: Public Perceptions of Barack Obama’s Race and the Effect of Obama’s Race on Public Support for His Presidency

While political pundits and academic researchers tend to emphasize Obama’s status as the first black President, this research finds that the Americans generally conceptualize Obama as mixed-race. A majority of whites and mixed-race Americans, and a third of blacks, conceptualize Obama as mixed-race. These Americans identify Obama as mixed-race to distinguish him from black people, interests, and values. Moreover, Obama’s perceived race has political significance; whites generally respond more favorably to a perceived mixed-race Obama while blacks respond more favorably to a perceived black Obama. Mixed-race Americans are more likely to perceive Obama to be mixed-race and also more likely to support Obama, presumably because of group commonalities they share. The group closest to Obama’s identity, mixed-race Americans who self-identify as black, respond most favorably towards Obama. These findings indicate that mixedrace Americans are actively supporting mixed-race public officials who share distinct commonalities with them. More importantly, the way most Americans conceptualize race appears to be changing dramatically to accommodate this emerging mixed-race population.
