All mental illnesses are not the same. They vary in intensity and duration of symptoms. Some sufferers will show periods of lucidity that can be confusing even to experts. Not all chronic sufferers from mental illness will have an acute psychotic breakdown, the type the College Park graduate student probably had. It is quite unpredictable when or if, acute psychosis will occur in any patient with mental illness. Although privacy rights have been grossly undermined in the age of the Internet, as a nation we claim we value privacy. To explore someone's thoughts and behaviors deeply requires a level of intimacy and time. Most college students are rushed. They are self-involved, trying to burn the candle at both ends, meeting deadlines for school work and often working one or two jobs to cover their tuition and room and board. To expect these students to recognize the symptoms of mental illness and to expect them to further separate the dangerous kind from the benign variety is pie in the sky. Let us say they did listen to your sage avuncular advice and became experts in the Diagnostic and Statistical Manual of Mental Disorders, then what? Do they dare interfere in the privacy rights of a student even if they suspect that the student is dangerously deranged?
