Is Deep State silencing Insiders that threaten 'UFOs are a National Security Threat' Narrative?

Recently, two insiders who had previously stated that some UFOs are reverse engineered spacecraft developed by major US  aerospace corporations were silenced in different ways. This Exopolitics Today Podcast examines the April 6 retraction by former Air Force Electronics Specialist, Mike Turber, of his testimony asserting the 2004 Tic Tac Incident involved classified Air Force craft being tested against the Navy's USS Nimitz battle group.  One week later on April 13, Mark McCandlish, widely known for his 2001 UFO Disclosure Project testimony about three Alien Reproduction Vehicles seen in 1988 at Edwards Air Force Base was found dead from a shot gun blast to the head.   The podcast examines these two separate incidents in light of the coming June 2021 Intelligence Community UAP report to the US Senate Intelligence Committee, and whether there's a connection given  they each threatened the emerging UFOs are a national security threat narrative that is being promoted by the mainstream media.
