Lee Harvey Oswald Was A Known Wolf

        So last week saw the release of many of the documents that had previously been held secret regarding the assassination of John F. Kennedy. The Daily Mail was pretty typical on its headlines:

• "Oswald met KGB agent in its assassin division in Mexico City's Soviet embassy two months before JFK was killed and was heard speaking in 'broken Russian' in intercepted phone call, files reveal."
• "REVEALED: J. Edgar Hoover insisted on trying to make US believe Oswald was sole assassin but Soviets thought Dallas cops were involved in the killing as crucial 300 documents are STILL withheld."
• "FBI informant claimed Dallas police officer J.D Tippit was the REAL JFK assassin - not Lee Harvey Oswald, secret files reveal."

But I haven't seen anyone comment on what I think is one of the most important pieces of information. From the first article cited above:

         Lee Harvey Oswald met a senior KGB agent months before the assassination of John F Kennedy, documents from the newly-released trove have revealed.  

         Oswald met agent Valeriy Vladimirovich Kostikov in Mexico City's Soviet embassy two months before the president was shot and killed in Dallas on November 22, 1963.
Kostikov was a senior agent in the 13th Department which was responsible for assassinations. 

         This was revealed in an intercepted phone call to the Soviet Embassy during which he was heard  speaking 'in broken Russian'. 

         Another document reveals the FBI was aware of the meeting on October 1 of 1963, more than a month before JFK was killed, meaning Oswald was already on their radar.  

In other words, the FBI was already surveilling Oswald, going as far as to wire tap his phones, and knew with whom he was going to meet in Mexico City, yet dropped its investigation of Oswald. The article mentions that Senators grilled some FBI agents about this after the fact, but it didn't appear that any satisfactory answers were given. There is a general rule to never attribute to malice what can be explained by stupidity, and that is probably the case here.
