The police of the Federal District are effective in handling crowds and quashing incipient disorders. They will be assisted by the crack Presidential Guard of the Army. Additional well-trained arery troops are stationed ln the Federal District and vould be available as needed.

The Mexican Government maintains surveillance over the activities of most of these groups and would probably have advance warning if any major disorders vere planned. Mexican legal procedures do not inhibit the police from detaining as many Individuals as the government considers necessary to maintain order on special occasions, and this license vill be exercised for the Vice President's visit.

6. In sum, we believe there ia little chance of an incident that would endanger the Vice President, and that the number of potentially embarrassing incidents will be small. One may not, however, rule out the possibility of an attempt at violence by some individual,sychopathanatic, who could be Mexican, American, or any other nationality.Original document.
