Reading the Scene in Ninety Seconds
You arrive alone at a reported fight outside a convenience store at dusk. In the parking lot you observe: two men standing apart, one holding his ribs; a woman filming on a phone; a silver sedan with its driver door open and engine running; a broken bottle near the sedan; a store clerk pointing at the man holding his ribs; and a third man walking quickly toward the side street. You have about ninety seconds before backup arrives. Your radio is in your hand.
1. Prioritize your observations and explain the reasoning behind the order.

Priority one is the departing third man, because he is the only element actively leaving the scene and evidence or a suspect can be lost in seconds. Priority two is the injured man, because medical need can be urgent and he is also the likely victim or the aggressor. Priority three is the silver sedan with the engine running and door open, because it is both a potential weapon and a potential escape route. Priority four is the woman filming, who is a witness and possibly a source of video evidence. Priority five is the clerk, who can confirm the report and identify parties. The broken bottle is noted but is not a person and can wait.
The reasoning is that people and moving vehicles change the situation, while objects do not. The departing man is the only irreversible loss. The injured man is the only medical risk. Everything else can be stabilized once backup arrives.
2. What do you do with the woman filming, and what observation about her matters most?
Read the worked answer
Treat her as a witness first and a potential evidence source second. She has a right to film in a public parking lot, so do not order her to stop or demand her phone. Note her position, whether she is close enough to have captured the encounter, and whether she is narrating, since narration often reveals what she believes she saw. Ask for her name and contact information and whether she is willing to share the video voluntarily. If she declines, document that and note that a warrant could be sought later.
The observation that matters most is her location relative to the fight and the sedan. If she was filming from beside the sedan, her video may capture the departing man's face or the moment the bottle broke. If she was across the lot, her footage may be too distant to identify anyone. Her position tells you how valuable the recording is before you spend time on it.
3. Backup is still two minutes out and the injured man begins walking toward the departing man. What is your move?
Read the worked answer
You are alone, so the priority is to prevent a second confrontation without creating one with yourself. Give clear, calm commands to the injured man to stop and stay where he is, and identify yourself. Do not chase the departing man and leave the injured man and the running sedan unattended. Use the radio to give dispatch a direction of travel and description of the departing man so other units can look for him.
If the injured man continues, position yourself between him and the departing man only if you can do so without turning your back on the sedan or the other bystanders. If he is seriously injured, medical care outranks pursuit. Once backup arrives, split tasks: one unit checks the departing man's direction, one secures the sedan, one interviews witnesses. The judgment being tested is refusing to chase one problem while three others are still live.
