We absolutely have the right to defend ourselves here in Australia. With guns even, no less.
I used to own several (bolt action, 5 shot internal magazine capacity) rifles because I used to competition shoot. I sold them off years ago because I stopped competing and just didn't need them lying around the house, rusting. There you go - freedom to own guns or not.
I could probably also get a handgun if I wanted, but I would need to renew my licence and pass strenuous background checks and prove to the police that I store it safely, AND I have to be a continual member of a gun club and shoot regularly with others so they can assess my gun handling skills (and I guess also my mental state) on a regular basis.
What I absolutely CANNOT do is to go and buy a semi automatic gun with a magazine capacity to slaughter an entire school room full of kids without having to reload. What the heck would _any_ civilian in a peaceful country want/need such a weapon? On the flipside, it also means I am free to enjoy the fact that my kids can go to school every day with a less than .001% chance that some maniac will walk into their classroom and mow them down.
To close off this post, and to end that illusion of "I can protect my family with a gun" hero storyline - About 3 years ago we had someone break into our house in the middle of the night. I was woken up by the sound of my son yelling at someone to get the fk out of his room so I jumped out of bed and grabbed a small wooden baton that I keep under our bed.
When I threw open our bedroom door, I saw a shadowy figure run past it in the dark corridor. To this day, I am glad I grabbed the baton instead of an (imagined, non existent) loaded gun, because my first instinct was let fly at the fleeing figure, only to realise a few seconds later that it was my own son, giving chase to the intruder who was fleeing ahead of him. I could have killed my own son if I had a gun in my hand in that split second of rage and confusion.
Later, we found out that the police nabbed the intruder, who turned out to be a 15 year old boy that lived a couple of streets away. Had I shot HIM, I would have had to live with the thought that I had killed someone's child. I cannot do that. I prefer to live with the _freedom_ of not having the guilt of taking someone else's life on my conscience.
