The article I linked to has a section on Australia; here&#x27;s an excerpt:<p><i>Evaluations after the reforms suggest that they saved lives. A study by Andrew Leigh of Australian National University and Christine Neill of Wilfrid Laurier University estimated that buying back 3,500 guns per 100,000 people led to a statistically significant drop in firearm suicides — 74 percent, in fact, with no parallel increase in non-firearm suicides.  ...<p>The results on homicides were a little less clear. Leigh and Neill found that the buyback resulted in a 35 to 50 percent decline in the gun homicide rate, but because of the low number of homicides in Australia normally, this change wasn&#x27;t statistically significant</i><p>I don&#x27;t have the numbers for Austrialia, but from the same article:<p><i>Nearly two-thirds of gun deaths in the US are suicides</i><p>If the proportion in Autralia are similar, reducing gun suicides, if not homicides, could save many lives.
