One of the detectives who came out of retirement to help with the LAPD’s investigation of RFK’s murder was a CIA spook. Dan Pena, the son of Manny Pena, talks about his dad in the video below:
Enrique Hernandez who worked on the case, is also alleged to have had ties to the CIA.
Both men spent time working for the US in Latin America aside from their jobs in the LAPD.
The CIA/Intelligence links could just be coincidental.
I find the forensic evidence in RFK’s case to be enough to conclude that there was more than one shooter.
