The American, identified in the report only by the name Dale, "nodded his head in an affirmative manner saying yes I know," the report said.
Numerous sentences in the DEA reports have been censored, including Harrison's name. The information is known to have come from Harrison because lawyers for defendant Ruben Zuno Arce asked Rafeedie to order the government to give them DEA interviews of Harrison that had not been provided earlier.
Both reports that have references to the CIA are stamped "SECRET, NO FORN," which sources said referred to no foreign distribution.
Harrison has testified that he decided last September to become a government witness in the Camarena case. He and his family have been relocated from Mexico for security reasons, according to government documents and his testimony.
On the witness stand, Harrison said that he audited classes at UC Berkeley in the late 1960s, first went to Mexico in 1968 at the height of a student rebellion there and settled in that country in 1971. Several defense lawyers in the case said they thought Harrison had been a CIA operative, but he denied ever having worked for a U.S. government agency.
