On the other hand, you are picking facts out of history that don't have a proven correlation to guns. Canada has banned household weapons with restrictive gun laws, and there haven't been any massacres there. Nor in New Zealand, Sweden, or England. Since you mentioned Australia, let me just say that you can't just compare two years of statistics because there are lots of variations in that data. If you want your stats to be solid, you need multiple year baselines compared to multiple years of data.
