Mental Health Crisis on an Overpass
At 2:15 p.m. on a Tuesday, dispatch sends you to the Route 9 overpass over I-95 for a man sitting on the guardrail with his legs over the traffic side. He is holding a folding knife and crying. A family member on scene says he is 28, has bipolar disorder, stopped taking lithium four days ago, and said he 'wants to end it.' Traffic below is heavy. The man does not respond to verbal commands and holds the knife to his own wrist. Backup is four minutes away. A crisis clinician is available by phone. The guardrail is three feet high; the drop is about 40 feet. He has not threatened anyone else. A small crowd is gathering on the sidewalk.
1. Does the officer have legal authority to take the man into protective custody under G.L. c. 123 § 12? What must be articulated?
Read the worked answer
Section 12 requires reasonable grounds to believe two things: the person is mentally ill and poses a likelihood of serious harm. The family's report of bipolar disorder and stopped lithium is relevant, but the officer must rely on observed behavior. The man is sitting on a 40-foot overpass with his legs over traffic, holding a knife to his wrist, crying, not responding to commands, and saying he wants to end it. Those facts establish a substantial risk of physical harm to himself. He has not threatened anyone else, so the danger-to-others prong is not the basis. The officer may take him into protective custody and transport him to a designated facility for evaluation. He cannot be held in a police lockup. The officer should articulate the specific statements and behaviors, not just the diagnosis, because the application will be reviewed by a clinician and a court.
2. What de-escalation and force options are appropriate, and what force is not?
Read the worked answer
The officer should treat this as a crisis negotiation first. Contain the scene, stop or divert traffic below, keep a safe distance, limit the number of officers in the man's view, and assign one communicator. Ask the clinician by phone for guidance. Use calm, short sentences, the man's name, reflective listening, and questions about reasons for living. Offer small choices, such as putting the knife down or sitting back from the rail. Do not rush him or crowd him; a sudden grab near the edge could cause a fall. Force is permitted only when objectively reasonable and necessary. Deadly force is not justified by a threat of self-harm alone; it would be justified only if the man posed an imminent threat of death or serious injury to others or the officer. A chokehold is prohibited unless deadly force is authorized. If he begins to cut himself or lunges, officers may use the least force likely to prevent imminent injury, such as a controlled tackle away from the edge or a less-lethal option if available.
3. What should happen after the man is secured?
Read the worked answer
Once secured, the first priority is medical care. Check for cuts, apply first aid, request EMS, and transport to the hospital. The officer should complete the Section 12 application and give the hospital the facts supporting likelihood of serious harm. The knife must be secured as evidence or safekeeping. Document the time, the clinician contact, the de-escalation steps, the force used, and the man's statements. Notify a supervisor if force was used. Body-worn camera footage should be preserved. The officer should also follow up on the family's safety and provide referral information. The man should not be charged with a crime merely because he was in crisis. If he made statements about self-harm, those should be included in the application and the report, not omitted as medical privacy.
