The way Roger Adelman sees it, making the transition from assistant U.S. Attorney to private practice should be relatively easy.

"As a prosecutor, if you really do your job, you try the case in your mind twice: You figure out in your mind how the defense will present the case," said Adelman, who has taught evidence and trial practice at the Georgetown University Law Center since 1975, and has participated in a variety of symposiums in the United States and abroad. "In that setting, you also have to develop and take both sides of the case."

Adelman recently left the office of the U.S. Attorney for the District after 18 years to become a partner in the Washington law firm of Kirkpatrick & Lockhart specializing in white-collar crime.

"Roger Adelman is a name any firm would like to add," siad Richard M. Phillips, senior partner at Kirkpatrick & Lockhart. "he is well thought of and will be a major asset to our organization."

"This is an excellent opportunity to do litigation work in a different direction," said Adelman. In his new position, Adelman said he will see a much broader range of clients, whose problems may involve both business interests and personal issues.

In his 18 years with the U.S. Attorney's office here, Adelman, 46, has tried and estimated 250 jury cases, including ones involving political corruption, conspiracy, bribery, fraud and murder.

Probably best known as the lawyer who prosecuted presidential assailant John Hinckley, Adelman also prosecuted former Rep. Richard Kelly (R.-Fla.) in the Abscam political corruption trials.

The departure of Adelman, follows the resignations of U.S. Attorney Joseph E. diGenova, which is effective March 1, and three other prosecutors in his office who had been directing investigations of alleged wrongdoing by the D.C. government. Adelman was not directly involved with the District government case.
