To be clear, this study looked at a large data set of shootings including non-fatal ones, and does not deny that black people are treated differently under the law. It also does not mean that the recent killings were not due to bias, just that the wider pool of incidents doesn't clearly support the conclusion that there is systematic racial bias in US police shootings.
