Funny you should mention this, OP. I just read something on this tonight. I've been diving down the MJ-12/Majestic 12 rabbit hole and ran across this in regards to whether to tell the public that we were in contact with aliens:
First Victim of the Cover-up
Secretary of defense James Forrestal began to object to the secrecy. He was a very idealistic and religious man who believed that the public should be told. When he began to talk to leaders of the opposition party and leaders of congress about the alien problem he was asked to resign by Truman. He expressed his fears to many people and rightfully believed that he was being watched. This was interpreted by those who were ignorant of the facts as paranoia. Forrestal later was said to have suffered a mental breakdown and was admitted to Bethesda Naval Hospital. In fact it was feared that Forrestal would begin to talk again and he had to be isolated and discredited. Sometime in the early morning of May 22, 1949 agents of the CIA tied a sheet around his neck, fastened the other end to a fixture in his room and threw James Forrestal out the window. The sheet tore and he plummeted to his death. He became one of the first victims of the cover-up.
