I think is going overboard in the other direction. And for purposes of probative value, for whatever it might be worth, in the absence of very definite negative evidence, I think it is permissible to say that in an exhibit such as 573 there is enough on it to say that it could have come, and even perhaps a little stronger, to say that it probably came from this, without going so far as to say to the exclusion of all other guns. This I could not do. 736

Although the Commission recognizes that neither expert was able to state that the bullet which missed General Walker was fired from Oswald's rifle to the exclusion of all others, this testimony was considered probative when combined with the other testimony linking Oswald to the shooting.

Additional corroborative evidence.--The admissions made to Marina Oswald by her husband are an important element in the evidence that Lee Harvey Oswald fired the shot at General Walker. As shown above, the note and the photographs of Walker's house and of the nearby railroad tracks provide important corroboration for her account of the incident. Other details described by Marina Oswald coincide with facts developed independently of her statements. She testified that her husband had postponed his attempt to kill Walker until that Wednesday because he had heard that there was to be a gathering at the church next door to Walker's house on that evening. He indicated that he wanted more people in the vicinity at the time of the attempt so that his arrival and departure would not attract great attention.737 An official of this church told FBI agents that services are held every Wednesday at the church except during the month of August.738 Marina Oswald also testified that her husband had used a bus to return home.739 A study of the bus routes indicates that Oswald could have taken any one of several different buses to Walker's house or to a point near the railroad tracks where he may have concealed the rifle.740 It would have been possible for him to take different routes in approaching and leaving the scene of the shooting.

Conclusion.--Based on (1) the contents of the note which Oswald left for his wife on April 10, 1963, (2) the photographs found among Oswald's possessions, (3) the testimony of firearms identification experts, and (4) the testimony of Marina Oswald, the Commission has concluded that Lee Harvey Oswald attempted to take the life of Maj. Gen. Edwin A. Walker (Resigned, U.S. Army) on April 10, 1963. The finding that Lee Harvey Oswald attempted to murder a public figure in April 1963 was considered of probative value in this investigation, although the Commission's conclusion concerning the identity of the assassin was based on evidence independent of the finding that Oswald attempted to kill General Walker.

Richard M. Nixon Incident

Another alleged threat by Oswald against a public figure involved former Vice President Richard M. Nixon. In January 1964, Marina Oswald and her business manager, James Martin, told Robert Oswald,
