Look for resources for litigators in Westlaw's AMJUR-TRIALS database. In this instance, resources for determining mental retardation, mental retardation evidentiary hearings and trials, the question of malingering, as well as debates about the Age of Onset requirements, can all be found in Capital Cases Involving Mental Retardation, 93 Am. Jur. Trials 1 (2008). Consult Lexis's Total Litigator Database for medical research and search by injury/disorder. While many jurisdictions consider diminished mental capacity to be a mitigating factor in capital cases, many lawyers have reported that jurors actually perceive it to be an aggravating factor. Consult medical journals about the rates of recidivism among mentally ill. Yale provides access to a number of useful journals electronically, including the Journal of Psychiatry & Law.
