I am afraid that this graph do not give a right value to this argument. The population of the U.S.A. is bigger than the population of Australia, therefore there is more people and more crimes. If you compared the amount of crimes they were stopped thank to a gun you will see that guns saved more lives than those lost. So place everything in the right perspective instead to be demagogue: you are comparing the rate of shoots of a country with 330 million people with a county of around 33 million people. Nonsense.
