My first book, The Digital Fourth Amendment, came out last month. I wanted to write some posts on the book over the next week. And I figured I should start with the most fundamental question: Why on earth did I write this book?

The thing is, I don't really believe in law professor books. I mean, I know they exist. But I've usually thought of most law professor books as a waste of time. First, most law professor books are too long and too dense. People might buy them and put them on the shelf, but does anyone actually read them?
