Cryptonym: LIRING-10
11/1/68 cable from Director to Mexico City: Identifies 201-776733 as LIRING-10. "...we believe LIRING-3 should be candid with LIRING-10 and tell him what and as much as he wants to know. We believe if LIRING-3 attempted (to) withhold or distort details (of) his imprisonment, it could be counterproductive to operation since LIRING-10 probably could check other sources for accuracy. There is no urgency for LIRING-3 make trip to (Cuba). We believe it more advantageous for him to remain Mexico and attempt become involved local (Cuba)/Guatemala exile activities. If, however, LIRING-10 suggests LIRING-3 go (Cuba), he should not hesitate do so."
