Wow, it's just saddening and revolting to hear of stories such as this. Nobody should ever be able to inflict physical and psychological pain upon us. It's frustrating to see, but I unfortunately think it will still be a few decades before we are free of this risk.
Because we live in an imperfect world, I'm surprised to find how I've gone from being extremely anti-firearm to getting self-defense training and also a legal multi-state concealed carry permit. Also important is consistent range time and practice. I feel safer carrying.
