I shall employ all means to right this gross mistake or injustice to a bon-fed U.S. citizen and ex-service man. The U.S. government has no charges or complaints against me. I ask you to look into this case and take the necessary steps to repair the damage done to me and my family.250

Even with the advantage of hindsight, this letter does not appear to express or imply Oswald's "determination to use a means, other than legal or peaceful, to satisfy [his] grievance" within the meaning of the new criteria.251

It is apparent that a good deal of further consideration and experimentation will be required before adequate criteria can be framed. The Commission recognizes that no set of meaningful criteria will yield the names of all potential assassins. Charles J. Gad, Leon F. Czolgosz, John Schrank, and Guiseppe Zangara--four assassins or would-be assassins--were all men who acted alone in their criminal acts against our leaders.252 None had a serious record of prior violence. Each of them was a failure in his work and in his relations with others, a victim of delusions and fancies which led to the conviction that society and its leaders had combined to thwart him. It will require every available resource of our Government to devise a practical system which has any reasonable possibility of revealing such malcontents.

Liaison with other agencies regarding intelligence.--The Secret Service's liaison with the agencies that supply information to it has been too casual. Since the assassination, the Service has recognized that these relationships must be far more formal and each agency given clear understanding of the assistance which the Secret Service expects.258

Once the Secret Service has formulated its new standards for collection of information, it should enter into written agreements with each Federal agency and the leading State and local agencies that might be a source of such information. Such agreements should describe in detail the information which is sought, the manner in which it will be provided to the Secret Service, and the respective responsibilities for any further investigation that may be required.

This is especially necessary with regard to the FBI and CIA, which carry the major responsibility for supplying information about potential threats, particularly those arising from organized groups, within their special jurisdiction. Since these agencies are already obliged constantly to evaluate the activities of such groups, they should be responsible for advising the Secret Service if information develops indicating the existence of an assassination plot and for reporting such events as a change in leadership or dogma which indicate that the group may present a danger to the President. Detailed formal agreements embodying these arrangements should be worked out between the Secret Service and both of these agencies.

It should be made clear that the Secret Service will in no way seek to duplicate the intelligence and investigative capabilities of the
