Twelve dead. Fifty-eight, I think it was, wounded. What's going on?
The answer, I'm afraid, is nothing much. Weapons are better than they used to be. Guns kill more quickly than swords. But human nature? Pretty constant, over the years.
The Colorado killer is a nut case, obviously crazy. But we've always had them; their tools are just better now.
The poet W.H. Auden wrote, "Evil is unspectacular and always human, and shares our bed and eats at our own table...."
Yes...so it was, so it is, so it will be...evil, everyday and always human.
