"I feel safe in my city knowing that somewhere out there - Trolley Man is watching over us."
Twitter comment by John Cameron on the terrorist attack in Bourke Street Mall in Melbourne. The terrorist stabbed one member of the public to death and injured two before eventually being shot by police, later dying in hospital. Homeless man Michael Rogers, 46, attempted to stop the knife wielding assailant by repeatedly striking him with a shopping trolley. A Go Fund Me page quickly raised $95,000 for Mr Rogers.
