As $600 million dollars are thrown by the Australian government to bolster anti-terror activities, it is worth considering the leading causes of death in Australia. These are from the Australian Bureau of Statistics (see also Crikey) and cover the years 2003-12.
Car accidents 8525 (not pedestrian deaths or accidents involving other types of vehicles)
Diabetes(indigenous Australians) 1690
Domestic violence (estimated) 850
Falling out of bed 417
Falling off ladders 230
Falling off chairs 198
Accidental gun discharges 190
Gastro and diarrhoea 168
Tractor accidents 137
TERRORISM (1978-2014) 113
Indigenous deaths in custody 66
Chicken pox 63
Whooping cough 20
Yes, in ten years more people died from gastro, or falling off ladders, chairs or tractors, than than those that died from terrorism over 35 years. Indeed, you have more chance of dying of chicken pox than terrorism.
