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.

Interesting new paper in @naturehumbehav.bsky.social. The authors conclude that variation in fatal police shooting rates across agencies is "far from random" and "primarily associated with...differences in crime rates, 911 call rates, officers per capita and the prevalence of guns."

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.*
