There are two main reasons why Ruby did this...
First was to accent the sheep-dipping of patsy Oswald in order to make him look like a true communist/Castro sympathizer...
Second was to look Oswald in the eye and remind him to maintain character in his his role playing as a crazed communist...And that one of the plotters could get right next to him to remind him...
which plotter was it? there was more than one? please post your evidence, as well as a video of the press conference, Albert. You need to zoom debate this, like Scott Kaiser and Hemming’s kid on Rob Clark’s video show. It was epic, i recommend it highly.
I wonder who you could find to debate, Albert? how about me? you could ask me all the questions you’d like about Crump and Mary Pinchot.
