After months of denial and finger-pointing by University officials, President Neil L. Rudenstine said yesterday he will ask the general counsel's office to reopen an investigation of charges of racial harassment within the University security guard unit.

In an interview yesterday, the president said the situation seems to be a "serious enough problem" to warrant "a fresh look," despite a similar probe last spring that found no wrongdoing.

Rudenstine said he would ask newly appointed General Counsel Margaret H. Marshall to examine the complaints by minority security guards after she takes office in November.

"Anytime you have complaints about potential problems of a racial sort...then you really must look at them," he said.

Rudenstine did not dismiss the findings of the University's original inquiry into the matter last spring, which cleared accused parties of all charges of racial harassment. Then-general counsel Daniel Steiner '54 said at the time that he found "perceptions" of racial harassment but not actual harassment.

Last spring, seven former and current minority security guards charged security supervisors Donald P. Behenna and Thomas F. Henaghan with harassment. The alleged harassment consisted mostly of verbal abuse and unusually close monitoring during shifts. Some guards also said Manager of Operations for Security Robert. J. Dowling ignored complaints against the supervisors.

Investigations of similar claims by two guards have been dismissed by a state agency, the Massachusetts Commission Against Discrimination.

"We're talking about a situation that's been looked at hard," Rudenstine said. He said he had no reason to doubt Steiner's findings, saying they "seemed to me to be very reasonable and carefully done, and I accepted them."

"But it seems to me that if the complaints have continued and there is a difference of views there, it's a serious enough problem to warrant another examination of a thorough and careful kind," Rudenstine said.

The president said Marshall, who as general counsel will oversee the police department, would meet first with Police Chief Paul E.Johnson. Johnson has repeatedly denied that thereis any problem in his unit, other than simply a"perception" of a problem.

If Marshall's investigation were to find racialharassment, Rudenstine said the supervisors wouldbe evaluated on a "case by case" basis. He did notrule out any disciplinary options, includingtermination.

Regarding Bill Clinton, who has promised tolift a ban on gays in the military, Rudenstinesaid, "I know what he said, and I don't disbelievehim...but you never know what's going to happen inthe dynamics of national politics."
