I also want to touch on the point someone made yesterday that claims Australia cracking down on guns didn't work. That's demonstrably false. Whoever came up with that talking point is either egregiously wrong or outright lying.
Since the 1996 Port Arthur massacre, after which Australia implemented tougher gun laws and a nationwide gun buy-back program, there have only been 12 mass killings (defined as having four or more victims) in the entire country. Of those 12, only four involved guns of any kind. Three of those four were domestic situations where someone only killed members of their own family. And in one of those three, the perpetrator killed his family with a knife and only used a gun to commit suicide. The other eight incidents involve either stabbings, arson, blunt instruments or automobiles.
So, since 1996, there has only been one incident in Australia where someone committed a mass shooting against strangers that resulted in four or more victims. I'll round that up to two since there was another incident at a university in 2002 where a student shot and killed two other students and wounded several others, though there's evidence that the perpetrator in that incident targeted at least one of the victims.
