The assassination of John F Kennedy on November 22, 1963, remains as one of the most controversial and debated in American history. Numerous conspiracy theories have emerged over the years, attributing the assassination to various motives. We will explore two of the most plausible theories that have gained traction throughout the years among historians and scientists.

The Umbrella Man Theory suggests that a man standing on the side of a road on a sunny day pulled out a black umbrella during the motorcade played a crucial role in the assassination. This seemingly harmless act raises suspicions among many conspiracy theorists who believe that the umbrella was used as a signal to the gunman involved in the assassination.

However, there are many significant flaws in the umbrella man theory. The man holding the umbrella was later identified as Louie Steven Witt, which denied having any involvement in the assassination. This conspiracy theory heavily relies on assumptions rather than evidence.

The Grassy Knoll Theory is one of the most controversial conspiracy theories surrounding the assassination of John F Kennedy. According to this theory, there was a second shooter located in a Grassy Knoll area near Dealey Plaza in Texas, who fired a shot and killed Kennedy. This theory is supported by eyewitnesses who heard gunshots and saw suspicious activity in the grassy knoll area.
Write a conclusion

In conclusion, while the assassination of John F Kennedy remains a topic of controversy and debate, the Umbrella Man Theory and Grassy Knoll Theory are two of the most well-known conspiracy theories that have gained traction over the years. However, upon closer examination, both theories lack substantial evidence to support their claims. The identification of Louie Steven Witt as the man holding the umbrella and his denial of any involvement in the assassination undermines the credibility of the Umbrella Man Theory. Similarly, the Grassy Knoll Theory relies heavily on eyewitness accounts that may be subjective and prone to errors. Ultimately, the true motives and culprits behind the assassination of John F Kennedy remain elusive, and the debate continues to captivate historians and scholars.
