Those massacres all occurred with semi-automatic guns. These are already (for all intents and purposes) banned in Australia. That kind of carnage just simply isn't possible with a bolt action rifle. It would be far easier and more effective to just drive a car/truck through a crowd, as happened in Europe.
The overwhelming majority of firearms deaths and crimes in Australia occur with illegal guns.To suggest that Australia's already tough gun laws need to be made even harder is a ridiculous knee jerk suggestion.
