After a mass killing in 1996 at Port Arthur where 35 people died and 20 were injured, Australia passed a comprehensive firearms act that didn’t ban guns but placed logical restrictions on them. Despite having a strong frontier gun culture, Australia went from a firearms mortality rate of 2.6 in 100,000 (one-quarter the U.S. rate) in 1996 to under one in 100,000, less than a tenth of the U.S. rate.
