Why, since you seem impervious facts...
Australia has a much lower murder rate than we do, even factoring in its smaller popuation...
They have a lower murder rate because of other factors, but looking at the change in crime rates, especially violent crimes of all kinds to include rape, armed robbery and armed assault, Australia's rates have gone up in most of them and are higher than ours in most categories.
The epitome of the issue was an discussion between Piers Morgan and some gun rights advocates, when Morgan asked if the solution to stopping a gang of criminals from doing a mob assault on a victim was to allow the victim to shoot the assaulters.
He simply could not see the justice, fairness or need for the victim to be able to defend himself. For him the victim being beat nearly to death was the preferable outcome rather than anyone, to include the criminals, getting killed.
He is the epitome of what is wrong with libtard thinking. US lower income people that have to work among dangerous criminals will not allow ourselves to be beaten to death while ass hats like Morgan are protected by their HEAVILY ARMED bodyguards.
