Poet and memoirist Reginald Dwayne Betts should be lauded as a true American success story. Following a conviction and 9-year sentence for carjacking in 1996 and following an awakening spurred by the book “The Black Poets,” Mr. Betts wrote two critically-acclaimed books of poetry and a memoir, got a B.A. and an M.F.A, became a Radcliffe fellow at Harvard and, last summer, graduated from Yale Law School.
