Results from a public opinion survey of knowledge, attitudes, and support for the insanity defense indicate that people dislike the insanity defense for both retributive and utilitarian reasons: they want insane law-breakers punished, and they believe that insanity defense procedures fail to protect the public. However, people vastly overestimate the use and success of the insanity plea. Several attitudinal and demographic variables that other researchers have found to be associated with people's support for the death penalty and perceptions of criminal sentencing are also related to support for the insanity defense. Implications for public policy are discussed.

John Hinckley, Jr. And The Insanity Defense: The Public's Verdict, Valerie P. Hans, Dan Slater

Cornell Law Faculty Publications

Public furor over the Not Guilty by Reason of Insanity verdict in the trial of John Hinckley, Jr. already has stimulated legal changes in the insanity defense. This study documents more systematically the dimensions of negative public opinion concerning the Hinckley verdict. A survey of Delaware residents shortly after the trial's conclusion indicated that the verdict was perceived as unfair, Hinckley was viewed as not insane, the psychiatrists' testimony at the trial was not trusted, and the vast majority thought that the insanity defense was a loophole. However, survey respondents were unable to define the legal test for insanity and …
