Awful news from Tuscson, Arizona, where Democratic congresswoman Gabrielle Giffords was just shot at point-blank range, along with at least six of her staffers, at a town hall event. Given the lack of details, one shouldn't jump to any conclusions, but this is exactly the sort of tragedy that so many people have privately (and some openly) been worrying about, as anger has increasingly suffused our national politics. I could be mistaken, but I believe Rep. Giffords was among those whose offices were vandalized during last fall's campaign. Few details yet on Gifffords's condition, that of her staff, the shooter or a possible motive. Here's hoping that this turns out not to be a politically motivated event, and that this terrible news doesn't get any worse.
Later Update: According to this eyewitness report, the gunman was tackled by a member of Giffords's staff.
