Your Constitution guarantees its citizens the right to keep and bear arms. This is possibly unique and a wonderful thing. Other nations' legislations essentially treat firearms ownership as a privilege and not a right and some may well prohibit it outright. Like all rights, and especially those protected by law, constant vigilance is required to ensure that it continues. Never take it for granted. As a non American, I sometimes find it somewhat perplexing at best, and disturbing at worst, to encounter an American citizen who is ambivalent about firearms ownership and the second Amendment, or worse, hostile to the idea of firearms ownership and safe stewardship of firearms. The nation's Founding Fathers well knew what they were doing, but of course presupposed that the foundation of the American Republic's Democratic experiment - of which the right to keep and bear arms are fundamental aspects - is, and was, based on a recognition and active awareness that such rights carried responsibilities that should never be taken for granted. Freedom is never freely achieved or preserved.
Seen in this light,the degree of firearms ownership in the United States is no accident and was perhaps, never meant to be an accident. It is part and parcel of the wider framework of the freedoms which its citizens enjoy - or should enjoy and a testament to the fact that an upright, law abiding people do not, and have never needed, large and over arching government because they have the legal and moral fibre, and through their ownership of firearms, the means, to preserve their freedom.
