Last week, the photographer Alex Levac and I visited the Balata refugee camp in the West Bank city of Nablus to investigate the circumstances of the killing of two innocent civilians in an operation by the army’s undercover counterterrorism Duvdevan unit. One was an 80-year-old woman who was innocently walking down the street. The other was a 25-year-old barber who was sitting at home with his family eating breakfast in the kitchen.
