WASHINGTON — Bill Murrain, a lawyer from Conyers, Georgia, traveled to the National Mall for the 20th anniversary of the Million Man March and stood side-by-side with three generations of black males: his sons, son-in-laws, and five grandsons. And last weekend, as Murrain walked near the White House, he spoke with pride about the accomplishments of black Americans over the years, which includes the historic election of President Barack Obama, the nation’s first African-American president.
