A new episode of Quality Policing is out. Check it out. We talk about many things including the DC body cam study that seems to show body cams don’t change anything. We beg to differ. Body cams just don’t change what people think they do. We don’t, however, talk about the details of the dirty gun squad in the Baltimore…

Quality Policing Podcast
Nick Selby and I have a new episode over at qualitypolicing.com. Among other things, we manage to have a rational debate about gun control. Imagine that. It’s Episode Five. (And yet somehow, from two people who claim to be good with numbers, we now have ten episodes.)

St. Louis and the acquital of Officer Stockley

What’s wrong with the Brennan Center’s analysis? There are many problems. But here are a few: 1) They take a non-random sample (which isn’t bad in and of itself) and then A) don’t tell the reader in the text and B) state conclusions as if the sample were a random sample (every data point equal chance of being picked), representative…

The Freddie Gray Effect in Baltimore

(If you think that’s easy or [that] can be readily downloaded, you’re wrong. Update: I could have saved a few hours of grunt work had I thought of using the …
