South Western Railway's campaign, developed by St Luke’s, aims to deter abuse towards its staff by highlighting the use of body-worn cameras. The billboard features a stark visual of a person seemingly being recorded, with the message 'Body cam footage is evidence. It pays to be kind.' This direct approach serves to raise awareness about the consequences of abusive behavior and promotes a kinder interaction with railway staff. The campaign's effectiveness lies in its simplicity and the powerful implication that every action can be recorded and held accountable.
