From an article in the Age/SMH today about Aboriginal paintings in the Northern Territory:
"Disturbingly, many images portray terrible conflict between Aborigines. Guse says the fact that many depict spearings is perhaps indicative of the cultural change that followed the arrival of missionaries."
Mr Guse, who is an archeological doctoral student from ANU, has apparently not heard of payback or the work of palaeontologist, Stephen Webb who studied skeletons of Aboriginal people and found widespread evidence of violence prior to European contact (bottom of page 152 here).
