Interesting that he claims to know something far different than all the news reports, video and photo documentation from the actual event, all of which until he came along were undisputed by anyone.
Classic progressive mentality.......when the facts are in opposition to what you want to be true you simply make up your own facts, claim some sort of moral superiority and use a host of logical fallacies to bolster an untenable, unhinged and untrue position. It would be amusing except these people can and do vote. Remember, when you argue with an idiot they will eventually drag you down to their level of stupidity and then beat you by experience. Your facts are indisputable but they won't matter to him. He will continue to make the absurd claim that he knows better than the photo documentation. This falls into the category of "I'll take Things that Aren't Actually True for $500, Alex".
