The ‘Oswald acted alone’ folks do not want to even hear about the broken up Chicago and Tampa attempts, (The similar in style to Dallas’s assassination, in early and mid Nov. 1963 as you know), it upsets their little ‘lone nut’ narrative to much!!!!! Some deny the first to attempts were in the works at all, or some of these ‘experts’ aren’t even aware of them!
My guess is none have even read much of the Warren Report and, of course, even if they had wanted to much of it was either not released or buried in the mountain of BS.
