The burden of insuring that appropriate action is taken to establish ethical standards of conduct for the news media must also be borne, however, by State and local governments, by the bar, and ultimately by the public. The experience in Dallas during November 22-24 is a dramatic affirmation of the need for steps to bring about a proper balance between the right of the public to be kept informed and the right of the individual to a fair and impartial trial. CHAPTER VI Investigation of Possible Conspiracy This chapter sets forth the findings of the Commission as to whether Lee Harvey Oswald had any accomplices in the planning or execution of the assassination. Particularly after the slaying of Oswald by Jack Ruby under the circumstances described in the preceding chapter, rumors and suspicions developed regarding the existence of a conspiracy to assassinate President Kennedy. As discussed in appendix XII, many of these rumors were based on a lack of information as to the nature and extent of evidence that Oswald alone fired the shots which killed President Kennedy and wounded Governor Connally. Others of the more widely publicized rumors maintained that Oswald must have received aid from one or more persons or political groups, ranging from the far left to the far right of the political spectrum, or from a foreign government, usually either the Castro regime in Cuba or the Soviet Union. The Commission faced substantial difficulties in determining whether anyone conspired with or assisted the person who committed the assassination. Prior to his own death Oswald had neither admitted his own involvement nor implicated any other persons in the assassination of the President. The problem of determining the existence or nonexistence of a conspiracy was compounded because of the possibility of subversive activity by a foreign power. Witnesses and evidence located in other countries were not subject to subpena, as they would have been if they had been located in the United States. When evidence was obtained from a foreign nation, it could not be appraised as effectively as if it had been derived from a domestic source. The Commission has given the closest scrutiny to all available evidence which related or might have related to a foreign country. All such evidence was tested, whenever possible, against the contingency that it had been fabricated or slanted to mislead or confuse.
