Gun-shooting case in Virginia

Did you hear the news of gun-shooting case in Virginia? The death toll of this tragedy was no less than 32. And then, the criminal committed suicide... This seemed to be the worst gun-shooting case in the history of America. I was surprised and shocked when I knew this because I'm a university student like the victim of the affair. In Japan, the law prohibit us from having guns, but Americans can get them easily. Although it can be a good way to defend themselves, we must not forget the danger of that system. I think it's a weak point of American society.
