who knows if true, but RFK presumably knew who was likely behind his brother’s death, so the idea he was killed at the direction of the same or a related party to his brother’s death isn’t that far-fetched.
Or, it could just be a coincidence that both brothers were assassinated by ‘lone gunmen’, which I don’t believe.
It’s a safe bet in my opinion,
Oswald - nut case
Sirhan - nut case
Hinkley - nut case
Guiteau - nut case
These guys had an overwhelming desire to be noticed. I’ve seen mass murderers pleased as pie with themselves after many years in prison. Hey, they are what they always wanted to be, seen to be important people.
Many other politically motivated political assassins and a few conspiracys. Conspiracy’s always fail to remain secret.
