I think this would probably deserve a thread of its own, to separate it from your general question about conspiracies, but ponder this if you will in reply to what you have said so far.
The Warren Commission was set up, and the principal appointees nominated, by the new President, Lyndon Johnson. He was a Democrat. Are you suggesting, therefore, that the conspiracy, if there was one, was also across party boundaries? I just find it curious that a self-confessed conspiracist should pick up on this point and say that it is "foremost" among your reasons for suspecting a conspiracy, considering what other "material" is normally trotted out. There must have been one heck of an inducement to keep ALL the Warren Commission workers silent, not just Ford. And keep them silent, to this day.
I would also like to know to what extent you consider the "conspiracy" to have reached. That is, is it a simple case of there being more than one gunman and, by definition, a conspiracy; or a conspiracy to cover up the "conspiracy" between two or more gunmen, because of the sensitive Cuban situation; or do you believe that the "conspiracy" amongst the government, military etc began earlier and that they were involved in the actual assassination plot?
