Just a reminder that after one mass shooting in Australia in 1996 at a historic site, the conservative PM John Howard pushed through legislation to enact national federal firearm regulations and restrictions, with the support of state premiers (including Rob Borbidge of QLD who lost next election)
Exactly.
Though Mr. Borbidge has never held public office after losing the state election largely because of his stance and just tends sheep, he does not regret supporting the enactment of the National Firearms Agreement (NFA). Since then, Australia has had almost no mass-shooting. Gun control works.
