Knife, Mental Health Crisis, and the Unlocked Door
At 9:15 p.m., Officer Grant is dispatched to a mental health crisis at a second-floor apartment. The caller, the subject's mother, says her 28-year-old son, Evan, has schizophrenia, stopped taking medication four days ago, and is holding a kitchen knife. She is outside. She says Evan is alone, has not threatened anyone else, and has been saying he wants to 'end it.' Grant arrives and sees Evan through an open window, pacing in the kitchen, knife in hand, talking to himself. The apartment door is closed but unlocked. There are no hostages, no other residents inside, and no reports of violence. Grant has a Taser and a patrol rifle in the car. Backup is five minutes away. Evan has not seen Grant. The mother begs Grant to 'go in before he hurts himself.' Grant must decide whether to make entry, set containment, or wait for backup and crisis negotiators.
1. Should Grant make immediate entry? Apply exigent circumstances and officer safety.

No immediate entry on these facts. Exigent circumstances require an objectively reasonable belief that entry is necessary to prevent imminent danger or serious harm. Evan is alone, no hostages, no threats to others, and the door is closed. Suicide risk is serious, but containment and time can reduce risk; a solo entry into a knife encounter is high-risk and may precipitate the harm the mother fears. Grant should set containment, call for backup and crisis negotiators, and enter only if Evan begins imminent self-harm or presents an immediate danger that cannot be addressed otherwise. The unlocked door does not create consent or exigency.
2. What containment and communication steps should Grant take while waiting for backup?
Read the worked answer
Grant should establish a perimeter, keep cover, and avoid standing in the doorway. Evacuate nearby apartments, request EMS staging, and get a description of the knife and the apartment layout from the mother. Use one voice, low tone, and simple questions: name, what happened today, what he needs. Ask about medication, prior hospitalizations, and whether he has harmed himself. Avoid shouting commands or challenging delusions. If Evan approaches a window or door with the knife, give clear directions and maintain distance. Document times and statements. Backup and negotiators should be requested early, not after a crisis.
3. Backup arrives and Evan moves toward the door with the knife. What force options and decision points apply?
Read the worked answer
If Evan moves toward the door with the knife, officers must assess threat, distance, cover, and capability. A Taser may be an option if lethal cover is present and the deployment is feasible, but a knife at close range is deadly. Firearms are justified only if the officer reasonably believes Evan poses an imminent threat of death or serious bodily harm to officers or others. The presence of mental illness does not lower the threat analysis but should inform communication. If Evan drops the knife or retreats, reassess and do not fire. Grant should coordinate, not act alone, and document warnings and force.
