I personally couldn't care less if Americans have guns or not, however I am very pleased that in Australia we have to get licenses to own a gun.
At least that way those that have a KNOWN history of violence or crime are unable to legally get them.
As was stated earlier, knives can also be used, but at least you can outrun a knife.
I must admit that I own a gun to kill snakes around my rural property, but otherwise would have no need for one.
I have noticed on this forum though that Americans tend to believe we have given up our freedoms by not being allowed to own guns. The opposite is true. I walk down the street never having a thought that I would ever be approached by someone with a gun. That for me is true freedom.
