Question: Ira stabbed his good friend, inflicting a fatal wound. At trial, a psychiatrist testified that Ira could not control his behavior, as he has a brain tumor that causes him to act violently. The doctor also testified that the condition did not impair Ira's ability to know what he was doing or that it was wrong. Assume that the jury believes the psychiatrist's explanation. Would Ira be convicted in a jurisdiction that uses the M' Naghten test? The irresistible impulse test? The Model Penal Code?
