Swomley further alleged in court that while at Harvard, Martin was among the guards who were "friendly" with management. Martin testified he had one friend in management.
Defendants Dowling and former security guard Timothy Carlow also testified Wednesday.
Dowling denied allegations that he had ever discriminated on the basis of national origin, noting that his mother was an immigrant who never became a United States citizen.
He further denied the allegation that he had ever supported the candidacy or the positions of David Duke, a politician and former Ku Klux Klan leader.
Carlow, whom the lawsuit alleges was the instigator of a fight with Abramian which led to Abramian's termination, denied he and Dowling had ever colluded to damage Abramian's career.
Carlow also testified about Thomas F. Henaghan, another defendant whom Abramian alleges harassed him over the course of three years.
Carlow said that Henaghan was "a real stickler for the rules."
"If he knew you were out of uniform or doing something at the same time every shift, he'd be there to get you," he said.
Carlow also acknowledged that a document which he filed earlier in the lawsuit proceedings was inaccurate.
He had indicated that while at Harvard he did not have any written warnings for disciplinary infractions. However, Carlow's personnel file showed at least one written warning and a number of memos detailing disciplinary infractions. Carlow testified he had not remembered the written warning and had filled out the interrogatory to the best of his ability at the time.
Harvard Reaction
In 1992, when a number of guards charged they had experienced discriminatory treatment, Dean of Students Archie C. Epps III said racial tension in the guard unit was "a serious problem" for the College. He told The Crimson that such tension might affect how guards treat students.
Now, however, Epps said he is "very pleased" with recent changes in the department such as required sensitivity training sessions.
Although Epps said that he is not familiar enough with the case to comment, he believes that many of the concerns which he expressed during the tumultuous period in which Abramian's charges surfaced have been resolved.
"My principal concern was that students of color not have to worry about how they would be treated and frankly I no longer have that worry," he said this week.
"I think [Chief of Harvard University Police Department Francis D.] "But" Riley has done an excellent job in changing the conduct of police in this area. I no longer have a concern about it," he said.
