The practice of ″horse shedding the witness″ (rehearsing testimony) is an example of such perjurious criminal conduct by an attorney, which is depicted in the true-crime novel Anatomy of a Murder (1958), by Robert Traver, and in the eponymous film (Otto Preminger, 1959), about a rape-and-murder case wherein are explored the ethical and legal problems inherent to the subornation of perjury.
