I found this in some of Teresa Lewis's court appeals: "Cognitive testing showed a Full Scale IQ of 72. Verbal IQ was 70, and Performance IQ was 79. This places the defendant in the borderline range of mental retardation (Borderline Intellectual Function)." What does this mean? Does it mean that a retarded person is held as accountable for thier actions as a mentally capable person? I hope not. I dont like that idea. I have a cousin who I dearly love but who just isnt wrapped to tight. She once shop lifted about $300 worth of antiques from an auction house. The thought of her having to be held responsible for some of the things she does scares me. A person with an IQ of 70 or lower is generally considered mentally retarded and ineligible for execution under a U.S. Supreme Court ruling last year.
