I can see what you mean there Rob, but the guns come in handy for many different reasons. Crime is not a major problem in my area of Texas. You'd be more likely to have someone mess with your car than actually try to get into your house. The fact remains that I am sitting at work at 3:50am and my wife needs something there to provide instant protection for both her and the kids. That's why I keep the guns within reach and I have the dog in the backyard. But the weapons are just for protective purposes; they are of great use when you are finishing off a buck that you put down, but is still too lively to take a knife to the throat. Better to put on in the head than take the rack to the rib cage. We also have a lot of rattlers, foxes, and coyotes moving closer into the city due to the lack of water in the county. If/when one of these animals (the 4 legged ones commonly carry rabies) gets too close to the house hold or my animals, they have to be taken down and I would rather do so without taking the bite to the arm, leg, or any other part of the body.
Sure, the guns help to prevent some unwanted guest coming into the house, but I was just pointing out that we use them for many more things around here.
Also, isn't owning a gun outside of law enforcement and farmers illegal in Australia?
