H.W. Bush claimed that the reason ~no more "conspiracy theories" after Ford was gone was because "No one can doubt the honesty of Ford"
So the implication of that is that anyone questioning the "Warren Commission" BS version is dishonoring the memory of this "great man" Gerald Ford, who everyone agrees is honest.
They always use the shield of the "mourning" / death / victim status to stop questions. He did this at a FUNERAL.
Remember H. Clinton with her "those who question Sandy Hook are blackhearts"
So it's sophistry. They use emotion to deflect questions. So the questioner is the bad guy.
Really those who don't question are the colluders.
