The rally took place on October 17, the shooting on February 29. Again, standard filmmaking techniques are interpreted as smooth distortion: "Moore works by depriving you of context and guiding your mind to fill the vacuum -- with completely false ideas. It is brilliantly, if unethically, done." As noted above, the "from my cold dead hands" part is simply Moore's way to introduce Heston. Did anyone but Moore's critics view it as anything else? He certainly does not "attribute it to a speech where it was not uttered" and, as noted above, doing so twice would make no sense whatsoever if Moore was the mastermind deceiver that his critics claim he is. Concerning the Georgetown Hoya interview where Heston was asked about Rolland, you write: "There is no indication that [Heston] recognized Kayla Rolland's case." This is naive to the extreme -- Heston would not be president of the NRA if he was not kept up to date on the most prominent cases of gun violence. Even if he did not respond to that part of the interview, he certainly knew about the case at that point. Regarding the NRA website excerpt about the case and the highlighting of the phrase "48 hours after Kayla Rolland is pronounced dead": This is one valid criticism, but far from the deliberate distortion you make it out to be; rather, it is an example for how the facts can sometimes be easy to miss with Moore's fast pace editing. The reason the sentence is highlighted is not to deceive the viewer into believing that Heston hurried to Flint to immediately hold a rally there (as will become quite obvious), but simply to highlight the first mention of the name "Kayla Rolland" in the text, which is in this paragraph. 
When was Kayla Rolland shot?
