Was CIA responsible for the assassination of President Kennedy?

John F. Kennedy was our 35th president of the United States. He was assassinated while visiting Dallas, Texas in 1963. He was riding in an open convertible. There were several buildings around Dealey Plaza. Then shots rang out and Kennedy was killed. It was later found out that the shots came from the Texas School Book Depository. There were about three shots that the people who were there heard.

Lee Harvey Oswald was arrested for his assassination, but before he could be brought to trial, another person, Jack Ruby, killed Oswald. The problem is that there have been many conspiracy theories about who was actually behind the assassination. Since Oswald died so quickly, it was difficult to determine his motive.
