Clicked through some of it: Russophobia already full-blown, whereby individuals are questioned even if they were in Sweden. For example Jonas Ridderstråle, who was questioned because of being overheard speaking of communism - which he admitted, because he was talking about what was in Swedish newspapers. So, wrongthink was definitely something that warranted questioning., There were accusations of his having travellled to Cuba, which he had not. https://www.archives.gov/files/research/jfk/releases/2022/104-10005-10125.pdf

Oswald was purported to have been photographed in Minsk (currently in Belarus), which was in the USSR at the time, in 1954. OOOOOH, must be a commie then. https://www.archives.gov/files/research/jfk/releases/2022/104-10003-10001.pdf

https://www.archives.gov/files/research/jfk/releases/2022/104-10336-10008.pdf This was a series of letters that question whether George H.W. Bush was in the CIA at the time (1963). On page 7 of 9, is a letter from J. Edgar Hoover saying 'george bush of the cia'. Investigators could not find any documentation. They did have a george w. bush in the cia, but not in the ranking to be mentioned by Hoover from what I understand. So, were records destroyed? idk
