As an outsider in a country where guns are illegal, I don't actually see any use in having guns for personal protection. I mean think about it. If guns are legal then it's pretty fair to say that burglars are going to carry them right? Is it usual in the US for burglars to carry guns? I expect so if they know the house occupants will have them. But put yourself into the situation for a second. You get woken up at 2am by the sound of your house being broken into. Your wife is next to you, the kids are sleeping next door, you panic. You grab your gun from the bedside drawer and go to tackle the burglars. Is this really the best thing to do? What if there are 3 or 4 of them? How many of you honestly think you could shoot and kill 4 people before 1 of them killed you? I know I couldn't. I don't think most people could unless they were a Police marksman and even that's doubtful. But the fact that you are tackling them with a gun is going to dramatically increase the chances of them shooting you. Don't forget, most burglars would rather not have to resort to violence. There is a big difference between getting a few years for burglary and getting life (or death) for murder. Why not just let them take what they came for, save the lives of yourself and your family and claim everything you lost off of the insurance? We are only talking about material posessions after all.
Put it like this, if Tony Blair legalised guns tomorrow, I still wouldn't want one.
It just seems to me that legalising fireams does little to protect the law-abiding citizens at home but much to augment the fear, violence and danger that we read about on those drug-ridden, gang controlled estates in places like Los Angeles.
