I read somewhere that not only was George H. W. Bush present at the Texas School Book Depository, as one of the principal overseers of the assassination, but that his teenage son, George W. was also present.

W. would have had no role to play that day. But his presence there would confer upon him a degree of insider status that would presumably guarantee his future and his loyalty to the cabal. It's quite possible that both Bushes joined the rank of potential Presidents that fateful day.
