"...in torts, liability is premised on fault; since the mentally ill are not in control of their acts they are not at fault and consequently, they should not be liable for their action. Such a superficially appealing resolution of this difficult problem, however, is not very convincing. Generaly the courts have rejected the mental illness defense to tort liability".
