I find that both Brussell and Emory do some excellent research into many issues. Unfortunately, neither Mae or David come/came to the conclusion that it was the Secret Service that took the shots on JFK. Mae focused on the "fascists" while, like Jones, Ventura, et al, Emory points to the grassy knoll for the fatal headshot.
 
    I do myself believe that the shot which hit Connally most likely came from the knoll, but I lack proof, and I have a slight intuitive inkling that it was George H.W. Bush that took that knoll shot( someone supposedly possessing Secret Service credentials located behind the knoll fence), but the fatal headshot did not come from the knoll, sorry!

   I do believe that much of the research done by Emory and Brussell fills in details having to do with the JFK assassination and other issues. It is well worth reading and listening to.
