I guess my best example is how people claim 9/11 was an inside job. All the evidence is made up of "mistakes" or inconsistencies that someone found by playing back the videos over and over in their basement.
I would think anyone with the means to fake an attack like that would be able to do so without making such trivial mistakes... but then lets say that it was totally an inside job. All those mistakes don't matter because everyone believes it anyways. This is similar to the Holocaust in the sense that a lot of people simply didn't believe it was happening because it was too crazy, too big of a thing to happen.
* want to say, I don't believe in that conspiracy at all, was more thinking out loud.
In regards to the UFOs... what benefit is there for the pentagon to put on this whole show? (Yes, I know ppl more or less asked for it but it doesn't mean they had to)
