https://www.wsj.com/articles/i-cited-their-study-so-they-disavowed-it-11594250254Here is probably the most important quote
In September 2019, I cited the article’s finding in congressional testimony. I also referred to it in a City Journal article, in which I noted that two Princeton political scientists, Dean Knox and Jonathan Mummolo, had challenged the study design. Messrs. Cesario and Johnson stood by their findings. Even under the study design proposed by Messrs. Knox and Mummolo, they wrote, there is again “no significant evidence of anti-black disparity in the likelihood of being fatally shot by the police.”
