Exciting to see the R files used to create this are attached and usable by anyone, so this measure can be tracked across time. As much as I can appreciate the benefit of having stories of individual cases of police misuse of deadly force for galvanizing activism and attempts at reform, I am not a big fan of emotional rhetoric as the main justification for a given policy stance. Relatively objective measures of how problematic the situation truly is seem far more practical to me, along with campaigns such as http://www.joincampaignzero.org/.
I am no statistics expert, so just curious, anyone here knowledgeable enough to read into the technical details and comment on how good the study quality seems to be?
