Indeed - that would be an awful derail - and we have other threads better suited for that sort of thing already. (plus, the nets are just chock full of resources pro and con, more than enough to occupy the rest of ones life if one were so inclined.) I will include here a single link, which details
100 things that Stone got wrong (according to this source), which is unlikely to change anyone's mind about the actual assassination, but will give one pause before buying anything Stone puts forward as factual. It's interesting reading, but I end my own participation here. I don't know nothin' bout it.
