WTF are you talking about??? It most likely was LBJ....and his wife who had the most to gain, imho.
The book “Family of Secrets” by Russ Baker is one source you should check out.
That GHW Bush is suspected of being involved in JFK’s murder is widely known.
Bush was at Dealey Plaza the day JFK was murdered, but when questioned regarding his whereabouts on that day, Bush tried to say he couldn’t remember where he was.
So Bush was clearly lying about where he was on the day of Kennedy’s murder. Photos show him to be at Dealey Plaza that day.
