I'm not saying it isn't a problem. But I'm 52 years old and my father was career military and my ex was career military and I have lived all over the US. I have never seen anyone shot.
I have had friends in middle eastern countries that marveled at my willingness to go grocery shopping alone at 2am as a woman. They couldn't believe that was safe and legal and I wasn't scared to leave the house by myself at that hour.
I have read all kinds of horrifying things about a great many countries. Every country has problems. There are no perfect countries.
And it seems to me that talking trash about the US while this incident is still live is just not exactly sympathetic pro social behavior. There are better times and places to hash out the fact that the US has a problem. I don't think guns per se are The Problem. But this is just not really the discussion where I want to debate the details with people.
