This I can agree with partially. It is extremely difficult to get a gun in the first place due to licencing laws in Australia, and they are never sought after as something stupid as "self defence".
It's that million year old right to own a gun that is getting people armed to the teeth and scared silly in the first place. It's that ridiculous that if someone has a rock thrown at them while sitting on their front balcony, that just "have the need" to own and AK-47 for "self defence", and all because they have the right to. Its the same mentality that people can just walk into K-Mart, buy all their ammo and then go rampaging.
Whatever you do, stop winging over nothing.
