Cryptonym: EMOTH
"On April 6, 1961, while a station officer was in Washington for consultation with Headquarters, he reported on events in the Dominican Republic and 'especially on the insistence of the EMOTH (dissident) leaders that they be provided with a limited amount of small arms for their own protection (specifically, five M3 .45 SMGs) (CIA memo for the record, 4/11/61)."

157-10011-10018: TRANSCRIPT DATED JUNE 11, 1975, TESTIMONY OF RICHARD M. BISSELL
5/29/61: Bissell testified that the State Department wrote through a CIA channel that "we must not run the risk of U.S. association with political assassination." Hinckle and Turner, above, at p. 112, wrote "the cable went out on May 29. On May 30, 1961, Trujillo's thirty-one-year rule ended when he was being chauffeured down the seaside highway en route to a rendezvous with his mistress. His care was overtaken and forced to a stop. He died fighting back."
