I don't know about you but I am kind of steering clear of all the response to the latest shooting in the US. But this article comes well-recommended. I skimmed it but it's from Overland Journal, so it would be pretty good.
One thing I will say about the shooting: what the hell were so many babies and young kids doing at a midnight showing of a movie? What the hell were so many babies and young kids doing at an M-Rated movie. Sure, the babies won't take any of it in, maybe they were asleep but wouldn't it be loud and noisy and crashy and scary? As it turns out, it really was.
