People believe in many things that are false. Particularly if they rely on long debunked and recycled Internet information. If you are truly interested in LBJ, then read Robert Caro's book "Passage of Power." Caro is the foremost historian on LBJ and has come to many negative conclusions about him. But he has found no evidence of his involvement in the assassination. Anyone can find something on the Internet to support their belief in Bigfoot, UFOs or JFK conspiracies but that does not give it any validity.
I agree with you. You can't believe everything you see on the internet and I know that, but with everything that I have found thus far, it has led me to believe that it was Johnson and his associates. The motive was for political gain, Johnson had always wanted to be president and him and Kennedy never really seen eye to eye. The opportunity was on his home turf, Texas. Johnson had many connections there and knew many powerful people to get the job done. The means was at least multiple shooters. There were links to the oil business and mafia. As for Oswald his statements and angle of gunshots just make no sense.
