When I was a boy, while watching the funeral procession of the Great Martin Luther King Jr. on NBC, I observed a rickety wooden cart being pulled by two mules and behind the cart, a sea of people. In the cart lay the body of MLK; at that moment, he represented the totality of the human struggle. I remember feeling then, while watching the procession on TV, that we, as a country, were either going to pull together or else come apart.
