A man walks towards me on screen and asks if I have a cigarette. I felt like answering him. People are waiting close by for the bus. A car approaches at speed, but it’s just dropping someone off. I’m prepared for the worst but he goes peacefully on his way. Then another car pulls up and, without warning, a man wielding a large knife suddenly charges in our direction after stabbing a passer-by. Even though I know this is not real, I feel a surge of panic, take aim and fire a series of shots. Unarmed civilians are close by.
