I recently attended a Wisconsin State Bar seminar, where speaker Egil “Bud” Krogh spoke of his experience as a former Nixon administration attorney, and his admitted involvement in illegal decisions. As noted in a WI Bar article:

Krogh authorized a covert operation to burglarize the office of Ellsberg’s psychiatrist to find information that would discredit Ellsberg. After his indictment, Krogh pled guilty to conspiracy to deprive individuals of Fourth Amendment rights under 18 U.S.C. 241. He refused to assert national security for a defense.

I found this evolution of facts concerning Mr. Krogh- and, at the Bar seminar, his humbled and detailed discussion of his mistakes, and namely his admitting responsibility for them- very impressive.
