Use of the insanity defense: A survey of attorneys in wyoming

Attorneys in the State of Wyoming were surveyed to determine their reported use of the insanity defense during the preceding 5 years. They were asked about the success, defined as “benefit to the defendant,” of the insanity defense at various stages that occur before trial. The attorneys reported that the insanity defense is used throughout the various stages preceding trial, with more use and benefit to the defendant being reported than previously suggested. This was particularly true for the earlier stages in the criminal justice process. The attorneys were also asked various attitude questions related to the insanity defense. Defense lawyers were more in from of the insanity defense and expressed attitudes that supported the insanity defense while prosecuting attorneys were relatively more opposed to the insanity defense and expressed attitudes consistent with this view.
