An F.B.I. advisory board voted this week to modernize an archaic definition of rape that the agency has used for more than eight decades in its tally of national crime statistics. The current definition used by the F.B.I., “carnal knowledge of a female, forcibly and against her will,” has been criticized by law enforcement officials and women’s advocates as far too narrow, with the result that many rapes are excluded from the yearly Uniform Crime Report. The new definition approved by the advisory board, which met in Albuquerque on Tuesday, includes the rape of men and crimes that involve oral or anal penetration or penetration with objects. The definition must be approved by the F.B.I.’s director, Robert S. Mueller III, before it is adopted.
