Chant in St. Louis after acquittal of policeman Jason Stokley: “hey ho, hey ho, these racist cops have got to go”

There is no evidence that Jason Stokley, the police officer who shot the black man in 2011, is racist.  But the perception is that blacks are being shot by white officers and the only explanation for it is racism by police.

Sunday’s crowd began peacefully protesting in the afternoon as demonstrators gathered in front of the St. Louis Metropolitan Police Department headquarters in downtown St. Louis at about 3 p.m. 

They chanted “hey ho, hey ho, these racist cops have got to go” and “black lives matter,” while also staging a die-in, in which participants lie down on the ground as if dead to protest police violence. . . .

Yet, the evidence suggests that there is not systematic shooting of blacks by white officers.  For the research, see this paper available here.

Do white police officers unfairly target black suspects?

Abstract

Using a unique new data set on police-involved homicides, we apply several discrimination tests to determine if white police officers discriminate against black suspects. We find that the probability of an unarmed black suspect being killed by a white police officer is significantly greater than the probability of a black suspect being killed by a black police officer. We also find that while black officers are generally more likely than white officers to kill unarmed black suspects at a higher rate than they kill unarmed white ones, the differences in these gaps for black and white officers are not statistically significant. These findings are inconsistent with taste-based discrimination on the part of white police officers.
