I guess I always figured stuff has been concealed simply for agencies and still living participants to save face. The redacted stuff probably shows incompetence, gross negligence and all kinds of despicable acts pulled by movers and shakers trying to take advantage of the vacuum created be a dead president. I mean Civil Rights advocate Lyndon Johnson *maybe* being a KKK member? Yeah, plenty of folks would want that kept under wraps. Perhaps Jack Ruby slipped an identified agent $100 to get near Oswald so he could shoot him? That would be redacted too, and something that sounds like a total low-level wanna-be monster move. I can't imagine Ruby killing Oswald was part of a high level conspiracy. First, the conspirators would have to be pretty confident a gunshot to the gut would kill Oswald, what were the chances, 50/50 at best? Then you need to be sure a 50-year-old man dies of cancer in jail before he decides to spill his guts? I mean that end game would have had be thought up at the local Jr. High locker room.
