The object is not to stop people from getting guns. That ship has long since sailed. The object is keeping them out of the hands of the people who are most likely to abuse their right to them. And that will require regulation. Just as it requires the regulation of all dangerous technology use to try and keep the people who should not be doing so from doing so. We require training and testing to operate cars, trucks, planes, trains, ships, and even fork lifts. Yet for some bizarre reason we think that machines that were designed to do nothing but kill people as quickly and efficiently as possible should require no oversight or regulation at all. Does this make any sense to you???
