You hit the nail on the head. Ruby was Anthony Accardos guy in Dallas.
The mobs fingerprints were all over this after they helped Kennedy steal Cook County and then Bobby went after them... Hard.
JFK’s father, Joseph Kennedy, worked with the mob his whole life.
Sam Giancana said, “The biggest crook I ever dealt with was Joe Kennedy.”
New York mobster Frank Costello said, “I made Joe Kennedy his money.”
During Prohibition Kennedy used his high class contacts to bring liquor in from Europe, which the mob then rebottled and sold in the US speakeasies.
They didn’t just steal Cook County for Kennedy. They waited an entire day past the deadline to turn votes until they knew how many votes Kennedy needed to win the entire state of Illinois. Then they turned their delayed “vote count” in to give Kennedy the state and the presidency. Having Bobby turn on them after that was a dumb thing to do.
Look up the name Harry Aleman.
