Last night i also heard on the ABC news that there are "Calls for tougher PNG gun control laws", and found some info
here.
The biggest problem is that regulation only effects the legitimate user, and has no real effect really on the criminal element who apparently still obtain weapons by whatever means and have no regard for human lives or the laws that are supposed to protect us from there actions.
Firearms don't kill people, people kill people, and if there were no firearms they would find yet another way to achieve their objective - then we would have all sharp objects, heavy blunt objects, and any other means banned so the population was protected - just another form of control - it would just become so ridiculous.
