On April 4, 1968, the Rev. Martin Luther King Jr. walked out on a motel balcony in Memphis, Tenn., and was felled by an assassin's bullet.

It is a poignant and hurtful thing to recall. But, now, 40 years later, circumstances provoke more than the usual reflection about this man, his life and our country.

Given what King lived and died for, and given his milestone civil-rights achievements in his short life, why are we still talking about race in the United States in 2008?
