Charles Freeman (defendant) had a long history of drug and alcohol abuse. In 1963, Freeman sold heroin to undercover police officers. Freeman was arrested and charged. Freeman was determined competent to stand trial, but he argued he lacked capacity to be found guilty for his actions. The district court applied the M’Naghten test for incapacity, which provides that to avoid criminal liability, a person must suffer from a mental disease or defect that makes him incapable of knowing the nature and quality of his actions or that those actions were wrongful. Freeman’s expert psychiatric witness indicated that Freeman had suffered bouts of toxic psychosis, delusions, hallucinations, convulsions, amnesia, and brain traumas related to his drug use and prize fighting. Nevertheless, the expert conceded that Freeman was aware that he was selling heroin but did not know it was wrong. The government (plaintiff) presented expert psychiatric testimony that even though Freeman’s drug use had dulled his thinking, he could still, with limitations, tell right from wrong. The district judge concluded that Freeman’s incapacity did not rise to the level required to satisfy the M’Naghten test and found him guilty. Freeman appealed.
