A new analysis of video clip footage supports official findings that JFK was shot by Lee Harvey Oswald

Peer-Reviewed publication


London, April 25, 2018 The long-held conspiracy theory that john F. Kennedy to be shot through a 2nd gunman ~ above the grassy knoll is wrong, according to a brand-new analysis of video footage the the shooting, published in the journal Heliyon. The results support the main autopsy findings: JFK endured a gunshot wound led to by the same type of rifle together that own by Lee Harvey Oswald, fired from the vicinity that the Texas School book Depository building located behind the motorcade.

You are watching: What is a grassy knoll

US President john F. Kennedy was assassinated ~ above November 22nd, 1963, while riding in a presidential motorcade in ~ Dealey Plaza, in Dallas, Texas. Lee Harvey Oswald was arrested soon after the shooting. A now widespread conspiracy theory posits that JFK was actually shot native a different location – the grassy knoll.

Dr. Nicholas Nalli, the author of the study and an elderly Research Scientist at IMSG, Inc. In the US, has been interested in the assassination due to the fact that he to be a child, and believes it is tho worthy of investigation today. “The divide JFK records were newly released, and the fate of a few remaining papers will shortly be decided,” that said. “Given the current trendiness that news that space not based upon facts, the study reflects that thorough scientific investigation can make a difference in supporting one theory over another, and also I thus believe that the object is as pertinent today as it was practically 55 years ago.” that said.

There to be several video clip recordings that the incident, and also one in specific shows the shooting in detail. The Zapruder film reflects the President’s head moving earlier and to the left, i m sorry Dr. Nalli shortly realized was as result of a recoil effect.

But he also detailed that observers had missed one crucial part the the evidence: the forward head snap in ~ the moment of the fatal cartridge impact. When analyzed using basic classical mechanics, the forward head snap, which is visible in the Zapruder film, offers proof that JFK was shot in the head native behind.

“Rather 보다 gloss end this fact, as has been done by many previous authors, including anti-conspiracy authors, I chose to study and also model that explicitly,” said Dr. Nalli.

He developed a basic one-dimensional gunshot wound dynamics model to explain the movements observed in the film. The version makes clearly calculations of the forward head snap that occurred before JFK’s head moved earlier and come the left ~ the gunshot. To execute this, the model uses recognized parameters indigenous the crime scene, including bullet mass, speed, and diameter, camera shutter frequency and autopsy measurements. This is the an initial time this element of the instance has been considered so thoroughly and quantitatively.

The calculations show quantitatively the JFK’s reaction after being shot in the head, as checked out in the film, are physically consistent with a gunshot wound brought about by a high-energy Carcano armed forces rifle (the evidence rifle own by Lee Harvey Oswald) fired native the vicinity the the Texas School publication Depository building (where Mr. Oswald worked) located behind the motorcade.

The findings perform not entirely ascendancy out a conspiracy, however they execute refute the most prominent theories that the deadly shot to be fired from the grassy knoll. They also oppose the idea the the Zapruder movie proves a conspiracy – in fact, the opposite appears to be true.

“I discovered that the Zapruder film shows President Kennedy being shot from behind and also not native the notorious grassy knoll, in corroboration that the main autopsy result – it is the only ‘smoking gun’ in the film,” stated Dr. Nalli. “The historical reality of the matter is the the us federal federal government investigations were consisted of of upstanding polite servants of high honest standards who, in despite the of daunting circumstances, by-and-large acquired the basics the the case correct.”

The models presented in the Heliyon file were emerged to apply to the Kennedy assassination, but it could have wider applications: the basic physical values could form a basic theoretical basis for expertise the wounding mechanisms connected in comparable dynamics.
