As a neuropsychologist, the vagueness of the term "mentally defective" concerns me. This is not a condition with specific diagnostic criteria, and creates the potential for broader interpretation and targeting of vulnerable populations. I understand the law currently refers to individuals who "cannot manage their own affairs", but this in itself is vague. Ten of the top 100 prescriptions written in 2014 were for psychcopharmaceuticals, including antidepressants and antipsychotics, representing over 50 million prescriptions. Would possessing such a prescription constitute a red flag? A documented diagnosis of depression, autism, agoraphobia or mood disorder? A stint in residential treatment for drug addiction or an eating disorder? I am in favor of gun control and universal background checks. However, given the short history of understanding and treating mental illness in this country (remember that the American Psychiatric Association (APA) removed homosexuality from its official Diagnostic and Statistical Manual of Mental Disorders (DSM) in 1973), I feel the order using this specific term should be repealed.
