If I had a dollar for single every time I saw someone say that X was a Y, but it turned out to be something else, I'd be a filthy rich man. Weitzman was a guy whose expertise with rifles originates from his yearlong stint winding down a chain of discount stores. That's it. On the other hand, we have the Alyea film of Day removing the rifle and the news photos of it being taken from the TSBD.
Of what you wrote, the parts that aren't baseless assertions are just circular logic. "I'm claiming there was a conspiracy, and if there's any evidence against what I'm claiming then it's because The Conspiracy made it that way."
Now you're sounding like the LNer that you are. Alyea was the person who said Fritz staged the in situ photo of the hulls? So is he a liar too? Then why do you consider his film gospel? Oh right, the LNer thing and your denial of any evidence against it.
