The dilemma

One officer hands the printout to her partner and turns to you. 'We'll need a statement at the station tonight. A full account of what you saw and what you did.' The man wrapped in foil watches you from the sand.

Your options

1. Say yes. You'll come in tonight and answer whatever they ask. They have a job to do, and so do you.
2. Tell her there isn't much to say. A person was drowning and you pulled him out. That's the only part you can speak to.
3. Ask if it can wait until tomorrow. You need to get home.
