What I've heard is it is likely both Ruby and Oswald were victims of MKUltra, and that both the CIA and Kennedy's own VP wanted him gone either A) because he was not in favor of contining the Veitnam War, or B) was going to declassify things they did not want declassified about Veitnam and other conflicts.
And Sirhan Sirhan's hit on RFK has all sorts of smells to it as well, which makes me think Sirhan was either a patsy or another MKUltra victim/asset.
I wouldn't be very surprised if it was found MLK's 'assassin' was also someone either used as a patsy to hide government involvement, given how the FBI and DC's elite treated MLK while he was alive, or that the shooter's motives may have included someone coercing them.
Just like the gov will always claim Epstein offed himself, they will continue to deny and hide any US gov involvement in JFK, RFK, or MLK's deaths, even when the laws passed by Congress mean they should be declassifying anything related to Kennedy's death.
