A recent research note by Benjamin Comer and Jason Ingram, a graduate student and an associate professor at Sam Houston State University, respectively, studied whether three sources of public data on police killings were consistent. They looked at Fatal Encounters, Mapping Police Violence, and the Washington Post’s data on the topic from 2015 through the end of 2019. Overall they found that these three sources were very similar to each other. This is the exact kind of research we need a lot more of - research that looks at the data we use and sees (basically) how good it is or how consistently different sources answer the same question. But there’s a problem. This paper is already outdated. It was outdated the moment it was submitted and is even more outdated now.
