I understand that POTUS put a limit on holding back the JFK files regarding those who are still alive. This must be about George HW Bush who not only called in with a tip as a Houston oil man named George Bush about someone else to offer an alibi for being in Dallas, but also someone who said that a George Bush had actually been brought down to the Dallas Police Dept. for questioning.
He was later "transferred" by other authorities and never seen again. I apologize for no sauce. It was something I read a month or two ago. I believe it was from a book written by a Dallas officer about that day in Dallas.
