CCTV genuinely helps the police with their enquiries. For instance, camera footage has aided their investigation of a missing office worker in Edinburgh, which has resulted in Lothian and Borders Police launching a murder inquiry. The cameras show 38-year-old Suzanne Pilley just outside her office in Thistle Street on the day she went missing. The force has employed unusual methods in order to jog people’s memories. These have included a large screen placed in St Andrew Square, which showed CCTV footage of her on the way to her office.
