One of my favorite Sherlock Holmes stories is "Silver Blaze" because Holmes used as evidence the fact that a dog didn't bark.
In line with my relentless "glass half full" way of looking at the world, I was heartened to read a piece on the Weekly Standard about Melissa Click, the faculty member at the University of Missouri who physically threatened a journalist who was filming her protest. Over 100 of her colleagues signed a letter supporting her. Glass half empty so far, right?
But take a look at the letter and the various departments represented by the signers. What department do you notice is absent?
