WASHINGTON (AP) — The Million Man March is remembered by many who were there as a watershed event, despite the fact that its impact on the way America regards African-American men remains an open question 20 years later.It was something the United States has not seen for decades: thousands upon thousands upon thousands of men, most of them black, congregated peacefully on the National Mall, clapping, cheering, testifying, promising they would work for a better future for themselves and their families.Nation of Islam leader Louis Farrakhan, who led the first Million Man March, will commemorate that event on Saturday with a "Justice or Else" march on the National Mall.
