NatGeo as well as the Smithsonian are heavily influenced by our government. Control the media you control the people.
All I need to know is how OPERATION MOCKINGBIRD worked. A clever way for our government to control the media. Put those in high positions into the CIA payroll. Sounds crazy right? Nope it happened and still is. Why do you think Wikipedia is always on top when people search something like this for information?
Great example is when you Google "OPERATION MOCKINGBIRD" you will of course see Wikipedia. And once again that site will be your first choice. They will use the word "allegedly" in their description. Why would they use that word when it DID HAPPEN? I know now you know. Glad I can open they eyes of how the system really works.
