As noted at Reason 24/7, the Federal Bureau of Investigation has done thorough investigations of the 150 shootings in which its agents killed or injured people between 1993 and 2011, and pronounced them all righteous. Sure, one incident resulted in the feds paying out $1.3M to Joseph Schultz, an innocent guy who had his face blown off by an FBI bullet, but it was still a good shoot.
Hey, the feds are pros. They don't make mistakes.
I went on RT to discuss this remarkable track record and the precedent it sets for how police departments around the country conduct their own scrutiny of shootings by police officers. I suggest that, perhaps, government agencies ought not be investigating their own actions.
