The Visitor Who Won't Leave the Lobby
A 14-storey office building has one lobby entrance, a reception desk staffed until 18:00, and turnstiles requiring a badge. After 18:00 a lone security officer sits at the desk and the turnstiles are left in free-rotation mode for cleaning staff. At 19:15 a man in a hooded jacket walks in behind a cleaner, sits in the waiting area, and says he is 'waiting for a friend on the 9th floor'. He gives no name and no company. He has been there 25 minutes. When asked to sign in he becomes loud, says the officer is 'harassing' him, and stands up. Two cleaners are mopping 6 metres away. The officer is 58, has no radio partner, and the nearest backup is a mobile patrol that can arrive in 10-15 minutes. The lobby has one camera covering the desk and one covering the doors; the waiting area is a blind spot. The man has not threatened anyone and has not touched anyone.
1. Assess the situation: what is known, what is unknown, and what risk factors matter most?
Read the worked answer
Separate fact from inference.
Known: unauthorised entry behind a cleaner; no name or host; 25 minutes in the lobby; refusal to sign in; raised voice; standing up; two cleaners within 6 metres; officer alone; backup 10-15 minutes; waiting area outside camera coverage.
Unknown: whether he has a weapon; whether he has a genuine contact on the 9th floor; whether the loudness is bluster or a precursor to violence; whether he is known to staff.
Risk factors that matter most:
- Proximity of bystanders. The cleaners are the highest-consequence element. Any escalation injures people who have no role in the dispute.
- The blind spot. Standing up moves him toward or away from coverage; the officer should reposition so both men are on camera.
- Isolation and response time. A lone officer cannot control a physically larger or younger subject, and 10-15 minutes is a long time if the situation turns.
- Behavioural trajectory, not volume. Loudness alone is weak evidence; standing up, closing distance, scanning exits, or clenching are more meaningful.
The officer should not treat 'no threat made' as 'no risk'. The correct frame is: what is the cheapest action that reduces the worst outcome?
2. What de-escalation approach and positioning should the officer use, and what are the trigger points for escalation?
Read the worked answer
Positioning: step back to create 2-3 metres and angle to the side rather than squaring up; keep the desk between them if possible; move so the waiting area is no longer behind the subject and both are in camera view; keep hands visible and empty; know where the door is without staring at it.
Communication: lower volume rather than matching his. Use his stated goal, not the rule: 'You're waiting for someone on the 9th floor - I can call up and confirm, and then you can wait in the seating by the door.' Offer a face-saving choice: sign in, or have the officer call the friend, or leave and return with the friend. Avoid 'you must' and avoid arguing about harassment; acknowledge it briefly ('I hear that this feels like a lot') and return to the practical step.
Bystanders: quietly wave the cleaners back or ask them to take the mop cart to the far corridor. Their withdrawal removes an audience and removes targets.
Escalation triggers: any movement toward the cleaners or the officer, a reach into the jacket, a verbal threat, blocking the exit, or refusal after two clear requests. At that point: withdraw behind the desk or out the door, call the mobile patrol and police, and do not attempt a physical escort alone. The officer's job is containment and calling, not hands-on removal.
