The Knife on the Porch
You are dispatched to a residential porch at 6:30 p.m. A 34-year-old man is holding a kitchen knife against his own throat. He is crying and says, 'Just shoot me.' His mother says he has schizophrenia and stopped taking medication four days ago. He has not threatened anyone else. He is 15 feet away. You have a patrol car for cover, one backup officer, a ballistic shield, and a less-lethal shotgun. A Taser is on your belt. The man occasionally presses the knife harder and says, 'Don't come closer.'
1. Outline your communication and de-escalation approach.

Use time, distance, and cover. Stay behind the patrol car, keep one officer as the primary communicator, and lower your voice. Ask his name and use it. Acknowledge his distress without arguing about whether he should feel that way. Avoid rapid commands, threats, and crowding. Ask what has helped before and what he needs now. Offer simple choices. Keep the mother nearby only if she can be safe and helpful, and ask her what usually calms him. Request a crisis-intervention team and keep the perimeter contained. The goal is to slow the encounter and create a chance for voluntary surrender of the knife.
2. When would force be justified, and at what level?
Read the worked answer
Force is justified only to prevent imminent harm. A threat of self-harm can justify intervention if the threat is imminent and no safer option exists. Deadly force is reserved for an imminent threat of death or serious bodily injury to the man or others. If he advances with the knife or begins a cutting motion, officers must assess whether less-lethal options-shield, less-lethal shotgun, Taser-are feasible given distance and reaction time. A Taser against a person holding a knife at the throat is risky and may not prevent a cut. The decision must be based on the totality of the circumstances, and officers should continue talking even while prepared to act.
3. What role should the family play?
Read the worked answer
The mother is a source of information and possibly a communicator, but she is not a tactical resource. Ask her about his triggers, medications, prior episodes, and what has worked. If she can safely speak to him from behind cover, consider it; do not send her into the open or use her as a shield. Keep her informed and away from the immediate action. Document her statements and any history she provides. Her presence may help calm him or may escalate him, so reassess continuously.
