The Knife, the Apartment, and the Twelve-Minute Wait
At 2:15 a.m., Officers Cole and Nguyen respond to a domestic disturbance. A woman outside says her boyfriend, Marcus, is inside their apartment and has a knife; she says he threatened to kill himself and 'might hurt anyone who comes in.' The officers see Marcus through a window in the kitchen, holding a steak knife at his side, crying. The apartment door is unlocked. Cole wants to enter immediately; Nguyen says they should wait for a supervisor and crisis negotiator, who is 12 minutes away. Marcus has not threatened anyone outside and does not appear to know they are there. The woman wants her medication from inside.
1. May the officers enter the apartment without a warrant? Identify the exception and its limits.
Read the worked answer
Rule: The emergency-aid exception allows warrantless entry when officers have an objectively reasonable basis to believe someone inside is seriously injured or imminently threatened with serious harm. Brigham City v. Stuart permits entry to render aid or prevent imminent violence. Application: Marcus has a knife, has threatened suicide, and has said he might hurt anyone who enters. That is a strong basis to believe he is an imminent danger to himself and possibly others. The unlocked door and the visible knife support immediate action. The entry must be limited to addressing the emergency-securing the knife, checking for others, and arranging medical or crisis care. Officers may not use the emergency as a pretext for a general search. Waiting 12 minutes for a negotiator may be reasonable only if the threat is contained and not escalating; if Marcus is alone and actively suicidal with a knife, delay itself can be deadly.
2. What tactical approach best balances officer safety and Marcus's mental-health crisis?
Read the worked answer
Application: The officers should contain the scene, use cover and distance, and avoid crowding the doorway. One officer should maintain lethal cover while another attempts calm, non-threatening communication from a safe position. They should request EMS and a crisis negotiator, but not treat the negotiator's 12-minute ETA as a reason to ignore an immediate suicide risk. If entry becomes necessary, they should announce, enter as a team, use available less-lethal options, and designate a lethal-cover officer. The woman's medication request alone is not an exigency; it does not justify a search or a rushed entry. The goal is to slow the encounter, reduce stimuli, and create time and distance while preserving the ability to act if Marcus advances.
3. If Marcus advances with the knife from about 15 feet, what force is reasonable, and what must the officers articulate?
Read the worked answer
Rule: Force is judged under Graham v. Connor from the perspective of a reasonable officer on the scene, considering the severity of the crime, the immediate threat, and whether the subject is resisting or fleeing. Deadly force is reasonable only when the officer has probable cause to believe the subject poses an imminent threat of death or serious bodily harm. Application: A knife at 15 feet can be an imminent threat if Marcus is advancing and ignoring commands. Officers should give clear warnings if feasible, use cover and distance, and consider a less-lethal option only if it can be deployed safely with lethal cover. If Marcus closes distance and refuses to drop the knife, deadly force may be justified. The officers must later articulate the distance, the weapon, the advance, the commands, the lack of containment, and why less-lethal options were not feasible or were unsuccessful.
