A story in Wednesday's editions of The Washington Post incorrectly reported that a double agent working for the CIA and FBI had delivered a package from espionage defendant David Truong to Vietnam's ambassador to the United Nations, Dinh Ba Thi. The double agent, Dung Krall, testified on May 1 that she had been shown a package of pictures by one of Thi's aides in New York that had supposedly been sent by Truong.But she did not testify that she had delivered packages to Thi.
An attorney for Ronald L. Humphrey, the United States Information Agency employe on trial for espionage, attacked the testimony of David Troung, his client's codefendant, yesterday, and elicited the information that Troung had once kept extensive notes on how to recruit sples.
Troung, a Vietnamese expatriate and student, maintained his innocence under withering questioning by Humphrey's attorney, Warren L. Miller.
The nores were part of his Asian s
In his questioning of Troung in Alexandra's U.S. District Court Miller held up note cards on which Troung had written that an agent should use rank influence, deception, friendliness and other means to "penetrate the opposition's secrecy apparatus."
Mille seemed to be trying, in the words of a final question he posed to Troung, to prove that Humphrey was "an unwitting dupe, unwitting agent" in the alleged spy network.
One exerpt from the notes read, "The nost desirable situation is where the source does not know he is in fact providing information to a foregn intelligence network.
"What did this note Troung made to himself mean? attorney Mille asked would be of "very little use." But Troung quickly replied that it Miller interjected that such advice might be aimed at influencing another to be an "unwitting agent."
Miller's questioning startled his own client, who hunched forward in his chair and frowned intently at Truong during his testimony. It occured as the last day of testimony began in the unprecedented trial.
The case is the first Vietnamese espionage trial following the Vietnam war and has become a test of the extent of authority the president has to authorize warrantless electronic surveillance during a national security investigation. Both Attorney General Griffin B. Bell and President Carter have personally authorized some goverment activities in the case.
The case has resulted as well in the unprecedented expulsion and subdequent recall of Vietnamese United Nations Ambassador Dinh Ba Thi. Thi was named as an unindected coconspiritor in the alleged espionage plot, which the Hanoi government labeled a "blatant fabrication."
But as Truong's defence attorney, Marvin D. Miller, pointed out yesterday, little or no evidence was presented linking Thi to the plot. A paid CIA informer, Dung Krall, testified that on one occasion she delivereda package to Thi from Truong at the Vietnamese misssion in New York, but she said she did not know what was in it.
Truong later testified that he voluntarily sent Thi public information on Vietnam that he was unable to get in New York.
The jury is expected to begin deliberations today on seven charges against Humphrey and Truong.
Humphrey and Truong are accused of funneling classidied diplomatic documents through a courier to Vietnamese representatives in Paris. Both men have pleaded innocent to the charges.
Humphrey is accused of stealing the documents from his USIA office and giving them to Truong. Truong is accused of passing the documents to the Vietnames with the intent of giving them an edge in negotiations last year between the United States and Vietnam.
Humphrey and Truong are charged with conspring with Thi and three other Vietnamese officials to injure the national defence of the United States as well as other related charges.
Each could receive a maximum of two life sentences and 35 years in jail if convicted.
Humphrey testified last week that he gave confidential classified State Department documents to Truong, a Capitol Hill lobbyist, out of his desperate love for his Viernamese common-law wife whom he calls Kim. She and her five children were trapped by the Communists in Vietnam.
Humphrey testified that he has hoped the information would aid in improving relations between Vietnam and the United States and that in some indirect way it would help secure the release of Kim and her children.
Truong has testified that he sent the information to Vietnamese friends inParis to use in their hewsletter. His goal was to help normalize relations between the United States and Vietnam, he testified, not to harm the United States or give an advantage to the Vietnamese in the talks, as the government has alleged. Truong said he was never a foreign agent and was never paid for giving information.
Throughout the trial attorneys for both men have made a point of attacking the substance of the cables, calling them information already in the public domain of harmless "diplomatic chitchat."
But government witnesses have steadfastly said the release of the documents to the Vietnamese would be injutious in part because they would reveal souces of information abroad.
Another center of controversy has been the testimony of Krail, the informat. Yesterday, Humphrey's attorneys re-called to the stand CIA agent Robert Hall, who was Krall's caseworker when she was an informer in the case. He was asked to rebut Krall's testimony that she never threatened to quit her work if she were not given a raise and never refused to perform some assignments if she were not given more money.
Hall testified last week that, indeed, Krall had aked for more money and benefits before she would complete some assignments, although krall had testified earlier to the contrary. Yesterday Hall repeated part of that testimony and added that Krall said she was going to write a book about her experience as a CIA and FBI agent.
Three other witnesess testified yesterday that Truong was an honest, truthful person.
Archimedes L. A. Patti testified that Truong had advised him on a book he was writing on Indochina between 1944 and 1946.
Under cross-examination, However, Patti said Truong had given him "Vietnamese propaganda" to use in his work. When asked where Truong got the information, Patti replied, "I suppose he got it from Hanoi."
But the more surprising evidence came in the note cards dealing with luring prospective spies that Truong said he copied from a book on World War II.
One of the passages on the cards said a prospective agent should be overwhelmed with rank.
"What does this mean," Warren sMiller asked Tuong, who testified as calmly as he had during the previous two days of testimony.
"My interest was to learn a little bit about the early practices of ther American CIA, how they handled their agent," Truong replied.
Miller then asked whether the use of rank could mean using high level contacts. Truong has testified that hehas many acquaintances in Capitol Hill.
"It could be." Truong said.
Part of another note said the" . . . source knows for whom he is working but is necessarily and purposely mislead . . ."
"When I wrote this down I was really interested in learning how the CIA operated in post World Was II," Truong said.
Another passage said "an gent is deliberately misled of the true purpose."
"What does this mean?" Miller asked.
"To me that means the CIA doesn't tell its agent what the true purpose of the mission is."
Another passage said a potential spy should provide material "so that the person doesn't know the information's ultimate destination."
"I was trying to find out how the CIA operates between here and Vietname," Truong said.
The 75-person capacity courtroom has been filled nearly every day of the 11 days of testimony by members of Truong' defense committee, former antiwar activitsts such as David Dellinger of the Chicago Seven, reporters, artists, Humphrey's family and others.
