Using random sites and media as your sole reasoning for a conspiracy is not logical. The media exaggerates, lies, and bends stories all the time. It creates no reasoning for a conspiracy. I could tell you that Obama isn't really president, because FOX said so. Still not true.
As I have said. A conspiracy is possible, as is the chance of a terrorist attack. However, you cannot be sure of either unless you have the government files. Which none of us will ever have. So it's speculation, on both ends. If you believe it is a conspiracy, great. If you believe it isn't, equally great. That does not mean you are right, it means you have an opinion.
Unless we see the classified files, we will never know for sure.
Don't mistake your information as correct just because it is information.
