From the Wall Street Journal:
In 1987, Michael Ryan went on a shooting spree in his small town of Hungerford, England, killing 16 people (including his mother) and wounding another 14 before shooting himself. Since the public was unarmed—as were the police—Ryan wandered the streets for eight hours with two semiautomatic rifles and a handgun before anyone with a firearm was able to come to the rescue.The author indicates that Australia has had greater success reducing gun homicides, but violent crime increased.
Nine years later, in March 1996, Thomas Hamilton, a man known to be mentally unstable, walked into a primary school in the Scottish town of Dunblane and shot 16 young children and their teacher. He wounded 10 other children and three other teachers before taking his own life.
... After Hungerford, the British government banned semiautomatic rifles and brought shotguns—the last type of firearm that could be purchased with a simple show of fitness—under controls similar to those in place for pistols and rifles. Magazines were limited to two shells with a third in the chamber.
Dunblane had a more dramatic impact. Hamilton had a firearm certificate, although according to the rules he should not have been granted one. A media frenzy coupled with an emotional campaign by parents of Dunblane resulted in the Firearms Act of 1998, which instituted a nearly complete ban on handguns. Owners of pistols were required to turn them in. The penalty for illegal possession of a pistol is up to 10 years in prison.
The results have not been what proponents of the act wanted. Within a decade of the handgun ban and the confiscation of handguns from registered owners, crime with handguns had doubled according to British government crime reports. Gun crime, not a serious problem in the past, now is. Armed street gangs have some British police carrying guns for the first time. Moreover, another massacre occurred in June 2010. Derrick Bird, a taxi driver in Cumbria, shot his brother and a colleague then drove off through rural villages killing 12 people and injuring 11 more before killing himself.
Six weeks after the Dunblane massacre in 1996, Martin Bryant, an Australian with a lifelong history of violence, attacked tourists at a Port Arthur prison site in Tasmania with two semiautomatic rifles. He killed 35 people and wounded 21 others.I would also note that, absent America's protective umbrella, Australia is now a sitting duck for any of its more populous neighbors (India, Indonesia, China, etc.) that decide to pursue a strategy of territorial expansion.
At the time, Australia's guns laws were stricter than the United Kingdom's. In lieu of the requirement in Britain that an applicant for permission to purchase a gun have a "good reason," Australia required a "genuine reason." Hunting and protecting crops from feral animals were genuine reasons—personal protection wasn't.
With new Prime Minister John Howard in the lead, Australia passed the National Firearms Agreement, banning all semiautomatic rifles and semiautomatic and pump-action shotguns and imposing a more restrictive licensing system on other firearms. The government also launched a forced buyback scheme to remove thousands of firearms from private hands. Between Oct. 1, 1996, and Sept. 30, 1997, the government purchased and destroyed more than 631,000 of the banned guns at a cost of $500 million.
To what end? While there has been much controversy over the result of the law and buyback, Peter Reuter and Jenny Mouzos, in a 2003 study published by the Brookings Institution, found homicides "continued a modest decline" since 1997. They concluded that the impact of the National Firearms Agreement was "relatively small," with the daily rate of firearms homicides declining 3.2%.
... In 2008, the Australian Institute of Criminology reported a decrease of 9% in homicides and a one-third decrease in armed robbery since the 1990s, but an increase of over 40% in assaults and 20% in sexual assaults.
