Police shootings per year, by outcome, included in this dataset. Keep in mind that upward trend is most likely a reflection of better record keeping.

Incredible new dataset on police shootings in the US, courtesy of Tom Clark, Adam Glynn, and Michael Leo Owens for their new book “Deadly Force: Police Shootings in Urban America.” It covers all cities with 100K+ residents and includes both fatal & nonfatal outcomes.

Chesapeake police lowers age requirement to address staffing shortages The Chesapeake Police Department says the ideal candidate is someone who is 19 and a half or close to turning 21 by the time they complete the police academy.

Where does that upper bound of 12000+ come from? Never seen an estimate that high with any publicly available data. Unless you’re counting people police nonfatally shot?

Unarmed killings are the rarest of these statistically rare outcomes, so it’s harder to pull a signal from the year-to-year noisiness. Plus, more undetermined cases in later years which mucks up the comparisons.

Julie, in your work with GVA, what was your sense of reporting disparities in rural v. urban areas, i.e., how likely is it that the upward trend is mostly rural areas being more likely to report on police killings now vs. 10 years ago?

George Floyd was killed 5 years ago. Expect news stories in the coming days that wrestle with why police killings continue unabated, despite all the reforms that have been introduced over the last 5-10yrs.

Oops: Trump-Musk Cuts Just Wrecked an NIH Org Championed by GOPers Republicans once lavished praise on an NIH center that deals with Alzheimer’s. Donald Trump and Elon Musk are hobbling it. What will they say now?

Scoop --> Trump-Musk cuts just resulted in the firing of numerous top researchers at NIH's center for combating Alzheimer's, sources tell me. They predict big setbacks to fighting dementias.

This cause was once championed by *Republicans.*

Police In-Service Training Podcast - Episode 5 | Justin Nix We discuss procedural justice theory and some of my own research on the topic.

I was recently a guest on a new podcast hosted by @policeinservice.bsky.social (professor of criminal justice at SUNY Buffalo State). We talked about procedural justice theory for ~28 minutes.
