Anybody who knows me will know that I crave explanations. It’s likely one of the things that’s so appealing to me about being a scientist. I’ve written about the confusion between explaining and justifying before. In fact, a post about this was one of the first things I wrote for Hitting Bregma. As much as I hate it, so many things go unanswered. Last night, many witnessed the deadliest mass shooting in America’s history. What we think we know is that a man named Stephen Paddock opened fire from a hotel room into a country music concert below. As of now, 58 are dead and more than 500 injured (unclear how many were injured by gunshot, and how many were injured in the frenzy during the shooting). This horrific event seems, at least for now, without explanation. For me, that makes it even worse than it already is.
