was the Kennedy assassination the result of a government conspiracy?

The assassination of president Kennedy took place on November 22nd 1963 in Dallas Texas. Ever since that day and that famously shocking event there has been a lot of talk in a lot of circles about a plot that was a foot to kill the president. It has been a belief that has lingered on since shortly after his death but is it real? Is it possible that there was such a plot? Most historians argue that it is highly unlikely.
Shortly after the assassination there were polls taken by various news organizations. They basically went right on the street and asked members of the public who just happened to be passing by the question. Do you think the president was killed as a result of a plot by the government to kill him? The results were that just about 2 out of every 3 people asked stated that they did believe in a plot to kill Kennedy.
Ususally the plot goes something like this. That the powers that be were not happy with JFK. People at the pentagon didnt like him, People at the FBI like J. edgar Hoover didnt like him, the CIA, Even vice president Johnson were all in it together to conspire to kill him so they could be rid of him because they were either just greedy for power or they just didnt like Kennedy's wild womanizing ways. Not only was there a plot involving several organizations in the federal government but these organizations were also enlisting the aid of various other foreign groups like the KGB, the cubans and Fidel Castro, and even the mafia in order to commit the deed. You have to ask yourself is having all of these groups involved in a plot like that even possible? These organizations that are mentioned above are all in some way or another natural rivals of each other. Some of them didnt even trust each other. The Cia working with the KGB to kill an american president sounds about as impossible as landing a man on the sun and returning him safely to the earth. We are talking about one of the most popular presidents in the history of presidents here arent we? You mean to tell me that out of all the thousands of people that would have been involved in an extensive plot like that there was not even one person in all of those government organizations whether he be high ranking or low ranking who actually liked Kennedy enough to go to the press before it happened and blow the whistle on the whole plot? There was no Mark felt (A.K.A. deep throat) who would have thought--hey wait a minute, this is a coup and its wrong and it cant be allowed to happen and would run to the press either covertly or openly and blow the lid off the whole thing before it happened? The other thing that bothers me about this theory about a plot is that its simply too complex to be even workable. You are talking about several organizations all working together at the same time to achieve the same goal and your telling me that the whole thing involving so many hundreds or thousands of participants went off without a hitch and the whole operation went like clockwork? You cant plan anything in this world involving more that two people that does not run into problems during your attempt to execute the plan but something as ambitious and complex as that went perfectly? It does not seem likely. That kind of a plot works great in the movies but not in real life.
The truth is plain to see if your willing to look at it. What does seem more possible to me is simply that the president was killed by a lone gunman. President Kennedy was killed by one man and yes there was a plot but it involved only him. Lee harvey Oswald was the killer of John Kennedy. He was a near expert rifle man from his years earlier in the military. They found evidence at his home that he had ordered a rifle thru the mail that was of the same type and style as the rifle found on the 6th floor of the Texas schoolbook depository which was where he worked. After the shooting all of the employees at the depository were accounted for except for Oswald who was missing. He was found about a hour later in a movie theater. When the police attempted to arrest him he tried to pull a gun on them and open fire. Later on at the famous impromptu press conference when Oswald claimed that the police were beating him and he had that famous black eye the reason he had that black eye was because he tried to resist arrest with a handgun and one of the cops at the scene tried to knock him out with a punch to the face to subdue him before he could get off some shots. Oswald's dislike of Kennedy was well known among both his family and friend as for he spoke of it often. He didnt like the way Kennedy was treating the cubans with all that talk about an invasion in the aftermath of the failed pay of pigs invasion in 1961. History afforded him an oppourtunity and he took it. The route that the presidential motorcade was going to take in Dallas was published in the local newspapers in the days before the event. Oswald simply noticed that the motorcade was going to pass in front of the building where he worked and on that day he sneaked a rifle into work. He wrapped the rifle in a plastic covering and went to work with it and said to others at work that they were curtain rods that he was going to install at home for his wife when he got home. When the presidents motorcade passed by the depository he fired three shots. He hit the president twice from a distance of about 250 feet. One shot was a direct hit on the presidents skull severely wounding him. He was sped away to Parkland Hospital where the doctors on duty claimed that he still was breathing and that he still had some faint vital signs and attempts were being made frantically to repair his wounds. He died less than 30 minutes later.
