From left, Queen Jackson, John Rankin and others march during the annual re-enactment of a key event in the civil rights movement in Selma, Ala., Sunday, March 5, 2017. Sunday marked the 52nd anniversary of the march across the Edmund Pettus Bridge over the Alabama River in Selma. On March 7, 1965, African-Americans seeking voting rights launched a march across the bridge en route to Montgomery but were attacked by police. That violent episode became known as “Bloody Sunday.” RSS/(Albert Cesare/The Montgomery Advertiser via AP)
