Obviously, you can't blame the hardware itself. However, there's no getting around the fact that the easy availability of firearms is a factor. Here, if you get mad enough, there's an implement ready at hand to settle the argument. This is not true in most civilized countries, so arguments don't get settled that way. The "X" factor, however, is something I've puzzled about for decades. Some other societies equal, or almost, in access to firearms. My Lord, in Switzerland, the rifle under the bed is required for large segments of society. They don't kill each other the way we do. We are a young country, in terms of culture. In terms of history, the frontier is close enough to touch. It lasted into the early 20th century. It was a society where "the law" was too far away to be helpful, so you solved problems with iron and lead. The problem is that we're now an urban country, overwhelmingly, and yet we still romanticize and glorify that era in our history. Series TV is literally soaked in it. Any evening, you can tune across the virtual dial and it's unusual if you don't see gun violence on at least one channel. Sorry for the rambling, but it's something I've considered for many years...
