On the Claim by Researcher, John Lott, that Unionized Police Are 65% More Likely to Use Lethal Force than Police Who Aren't Unionized - https://townhall.com/columnists/johnrlottjr/2018/08/27/police-shootings-n2513363

Lott admits that the stats are preliminary and that there could be some confounding elements involved (urban versus rural, for example)......but it does make sense when you realize how the union has a tendency to protect bad officers. Something to think about, at least.
