"In fact, according to the Australian government’s own statistics, a number of serious crimes peaked in the years after the ban. Manslaughter, sexual assault, kidnapping, armed robbery, and unarmed robbery all saw peaks in the years following the ban, and most remain near or above pre-ban rates. The effects of the 1996 ban on violent crime are, frankly, unimpressive at best. By the way, reporters love to claim that there have been “no mass shootings” in Australia since their restrictive gun law went into effect in 1996, but that simply isn’t true."
At Monash, seven people were shot (two fatally) by a murderous student who was armed with multiple handguns. All six handguns were acquired legally. The attacker was later determined to be mentally ill. The Hectorville siege that saw seven people shot (three fatally) was conducted with a shotgun that was legal under Australian law. The attacker in this incident was also found to be mentally ill. The Hunt family murders were likewise carried out with a legally-owned shotgun. The murderer in this instance was thought to be highly stressed due to his wife’s head injury.
