As the Secret Service deputy assistant director (Uniformed Division), Office of Protective Operations, I am indeed disturbed by an article by William Raspberry {op-ed, Dec. 9}.

It is obvious to this agency that Mr. Raspberry in his haste to release his column did not bother to do research that would have enabled him to put together an accurate portrayal of what occurred on the date that the children of Peace Bird visited the White House.

If Mr. Raspberry had done his research, he would have learned that when the children did arrive at the White House they were instructed to proceed to the Old Executive Office Building, a part of the White House complex, where the symbolic flowers of peace could be accepted. The children's group decided not to do so and left the flowers on the ground outside the White House gate. At no time did any uniformed officer of the Secret Service advise the group that the flowers could not be delivered to the White House.

As the agency responsible for the protection of the president, the Secret Service strives to maintain the safest possible environment for the president, as it is mandated to do by law. In addition, we expect our personnel to perform their duties in a professional manner at all times. The men and women of the United States Secret Service Uniformed Division are among the most professional law enforcement officers in the world today. It is indeed disturbing to learn that one writer, through his inaccurate reporting, can tarnish the reputation of the Secret Service Uniformed Division.
