The Wellington mosque massacre proves that gun control works
The Wellington mosque massacre proves that gun control works. After the 1996 Port Arthur massacre in Tasmania, and the killing of two students at Monash University in 2002, Australia required that all gun owners have licenses and all guns must be registered. The Australians haven't had a mass shooting since.
That's why Brenton Tarrant, an Australian, had to go to New Zealand, where there is no ban on semi-automatic weapons, to perpetrate his massacre.
