Let's pick out a good one (so many to choose from): Dr. Pearcy says "The Sixth Floor Museum" is a "false flag operation". A false flag? That makes no sense to me unless by "false flag" he simply means a covert operation or program. An operation run and directed by who? My understanding is that a "false flag" is an act done by one party or group in disguise that is intended to implicate a second party in the act. So a group of soldiers in disguise commit an act - massacre civilians - in order to make it look like another group of soldiers committed the crime. That is a deception, a ruse involving an act or acts. So how does this definition apply to the Museum? The Museum is pretending to be who? To blame who for what?
Okay, so the museum is simply a covert operation; forget the "false flag" nonsense. That means people like Gary Mack and others who work(ed) in the museum are or were willingly (I assume?) part of a covert operation? Agents acting on behalf of the CIA? They are lying to the public, engaged in deception. For decades. And right now. Today. As you read this. Whew.
What is his evidence for this claim? It's a pretty serious allegation. Dr. Pearcy is not simply some guy on the internet (like me; and you reading this). He's an accomplished person making public statements. Again, he's accusing the people at the Museum of being frauds, of lying about who they are. And lying about murder. Of the President. Of the United States. And his evidence is?
This is the same Dr. Pearcy who is upset that Fred posted a picture of him with his dog but is fine with accusing all sorts of people of lying for the murder of the President. Does he not see the problem here?
