When you look at the Church Committee, Frank Church was the chairman and Frederick Schwarz Jr. was the chief counsel (I bet you've never heard of Frederick Schwarz Jr. until now). With this committee, Church is always portrayed as the leading figure in it when this committee is referenced in articles and books.
However...
A different matter arises when it comes to the HSCA investigation. With the HSCA investigation the chairman was Louis Stokes and the chief counsel was Robert Blakey. Yet for some reason when the HSCA investigation is referenced in articles and books, it is almost always the chief counsel Blakey that is cast as the leading figure of this investigation rather than the chairman Louis Stokes.
Why is this? Why does Blakey get the spotlight over Stokes when it comes to the HSCA?
