People with mental illnesses should never be imprisoned as the negative environments and lack of mental health services/resources often worsen their disorders. Mentally ill offenders need more intensive treatment and counseling, not prison. Prisons do not facilitate rehabilitation and they are damaging, especially for the mentally ill.
This teen had previously attempted suicide before the latest attempt and the MYC staff were aware of her struggle with depression. She should have been moved to the observation room with better visibility or better yet, to the mental health hospital. She should have been receiving mental health treatment and counseling as opposed to being locked in a cell with limited access to those services.
