Motivation is one key element of a crime, especially murder.
so here’s three scenarios and you will see that yours is just a delusional as the others, probably more so.
1. The president and his brother after winning the election with mob help, prosecuted the mob even kidnapping Marcello off the street and dumping him in Guatemala. nobody ever treated Marcello that way and his boss in chicago may have not been pleased. just a guess. you know mafia guys are sensitive about being disrespected. The mob was fed up and decide to kill him after their father stroked out and couldn’t stop them.
2. LBJ was older than kennedy and less popular and very ambitious and not used to being lreagted to state funerals. He rabidly ewanted to be president. He hated the kennedy’s personally to boot and they treated him with disdain. by the way there are hundreds of witnesses to this. Kennedy went to Dallas and LBJ had him killed just as he had hired hit men in the past and stolen elections. and he made statements to witnesses that things were improving soon. Do you think this was reference to interstate Hwy repairs?
3. Lee harvey Oswald worked in a building where the president’s car coincidentally came by after the route was recently changed and he shot him and the top was off the limo. he must have known that when he brought the rifle to work ahead of time, huh. Then Ruby shoots him from in front, in the PD garage. coincidentally the three cops escorting him were on each side and the back, escorting the most notorious suspect since Booth. No one in front. Ruby says he loved jackie. maybe now that her husband was dead, he would have had a shot at her and he benefited from the assassination.
You cannot prove everything, but you have to consider motivation and as my father said when we watched Ruby shoot oswald, they shut him up forever. if they wanted him to talk they would have protected him.
Speculation is not proof.
