"It can be established conclusively that Sirhan did not shoot Senator Kennedy. And in fact, not only did he not do it, but he could not have done it."
Tomorrow is the 44th anniversary of Robert Kennedy's assassination, so I thought to post a flashback story, since many people still believe the myth of the 'lone wolf'.
According to this ABC news report, two scientists claim to have confirmed that at least 13 shots were fired, though Sirhan Sirhan had only an eight shot revolver and didn't reload.
Moreover, a witness, Nina Rhodes-Hughes, heard 12 to 14 shots and insists that there was another shooter, but the FBI CHANGED her testimony to say she heard only eight shots.
"I never said eight shots. I never, never said it. There were more than eight shots. There were at least 12, maybe 14.
And I know there were because I heard the rhythm in my head," Rhodes-Hughes said.

The FBI covered up fact there was a SECOND gunman...

Robert Joling and Phillip Van Praag claim their analyisis of the audio shows that at least 13 shots were fired, though Sirhan's gun held only 8 bullets.

"New evidence underscoring how a ‘rush to judgment’ led to failed justice in the Robert F. Kennedy assassination

Robert F. KennedyThis book presents, for the first time, exclusive details on the Van Praag discoveries scientifically establishing the presence of a second gun in the RFK assassination. A portion of these discoveries became the basis of a recent Discovery Times Channel television documentary. Since that time, an additional discovery adds a greater depth of verification and understanding to what occurred in that kitchen-pantry 40 years ago.
For the first time, Dr. Robert J. Joling, J.D., presents details of his almost 40 year involvement in this case. Coverage is included of meetings with key principals such as medical examiner / coroner Dr. Thomas Noguchi (who performed the autopsy on RFK), victim Paul Schrade, and various medical, police and judicial entities. As a judge, trial lawyer, friend and counsel to a number of involved parties in this case, Dr. Joling provides a unique perspective on the events and previous findings associated with the assassination."

"Just like JFK, RFK was killed by a conspiracy - NOT a lone nut. Here's the latest on Sirhan.http://www.edition.cnn.com/2011/11/26/justice/california-sirhan-rfk/inde...

Los Angeles (CNN) -- Sirhan Sirhan, convicted of the 1968 assassination of presidential candidate Sen. Robert F. Kennedy, should be freed from prison or granted a new trial based on "formidable evidence" asserting his innocence and "horrendous violations" of his rights, defense attorneys said in federal court papers filed this week.

In a U.S. District Court brief, Sirhan's lawyers also say that an expert analysis of recently uncovered evidence shows two guns were fired in the assassination and that Sirhan's revolver was not the gun that shot Kennedy.

Attorneys William F. Pepper and Laurie D. Dusek also allege that fraud was committed in Sirhan's 1969 trial when the court allowed a substitute bullet to be admitted as evidence for a real bullet removed from Kennedy's neck.
