I read the posted article.
You sound as though your mind is made up. This author posted, previously, that people whose minds are made up cannot have them changed. I expect that this is true.
I believe that my mind is made up that a “lone gunman” is a myth - a near impossibility. It is far easier to believe they had help and the search for that help is the search for evidence.
I also believe that this same scenario just played out in Butler, Pennsylvania. Since I don’t like the idea of a rogue bureaucracy and repeated assassinations, I would prefer to find answers, rather than bury my head in the sand.
If you had been alive back then, you would have known the Oswald was not stationed at Atsugi when there were U2 flights over Russia. Those stopped in the Spring of 1960 when Francis Gary Powers U2 was shot down over Russia.
And as a Marine Corp private, one who was constantly in trouble with his superiors, there was no chance that Oswald had any information on the U2, which in those days was a CIA, US Air Force operation.
But I’m glad you read the article.
