Mass murder.

The news that thirty-three students died when a mass murderer walked through a Virginia college shooting people will be labelled " only in America " by some.
That conveniently forgets that a similar event happened here when Martin Bryant strolled through the grounds of Port Arthur in Tasmania and executed thirty five people - all strangers - for no known reason.
Bryant was armed with two self loading assault rifles. The killer in America used two self loading pistols.
Australia has tightened gun laws and it is now more difficult to legally have permission to own rifles and shot guns - but we have a dangerously expanding trade in the illegal import of hand guns.
In past decades the big money was in importing drugs. Heroin was the drug of choice and those at the top of the importing pyramids became fabulously rich - but things changed. The penalties for drug importation tightened and at the same time heroin went out of favour, replaced by synthetic drugs can can be brewed locally.
The opportunity for large profits switched to the importation of hand guns. There was a ready market from ethnic gangs and the penalties for getting caught were far less than for importing drugs.
Australia is fast acquiring a gun culture. For gang members the acquisition of a hand gun is synonymous with respect and attaining a place in the pecking order.
Only the deranged indulge in mass murder - but if we allow a hand gun culture to multiply it is inevitable that sooner or later one of those deranged will go on a shooting spree similar to the one Martin Bryant conducted in Tasmania. If hand guns are available - sooner or later one will fall into the wrong hands.
