"There is only one kind of people that would go to such extremes"

” . . . Don’t believe the Warren [Commission] Report, that was only put out to make me look innocent. . . . I’m going to die a horrible death anyway, so what would I have to gain by writing all this. So you must believe me. . . . that [sic] is only one kind of people that would do such a thing, that would have to be the Nazi’s [sic], and that is who is in power in this country right now. . . . Japan is also in on the deal, but the old war lords are going to come back. South America is also full of these Nazi’s [sic]. . . . if those people were so determined to frame me then you must be convinced that they had an ulterior motive for doing same. There is only one kind of people that would go to such extremes, and that would be the Master Race. . . .”  Jack Ruby -- Letter smuggled out of prison
