FILE &#8211; In this Oct. 10, 2015 file photo, a man wears a hoodie which reads, &#8220;Black Lives Matter&#8221; as stands on the lawn of the Capitol building on Capitol Hill in Washington during a rally to mark the 20th anniversary of the Million Man March. Fifty years ago, Martin Luther King Jr. asked Americans, &#8220;Where do we go from here?&#8221; His warning of chaos or community squarely confronted racism, and marked a shift from his emphasis on nonviolence to a demand for full economic and political equality. Younger generations of black activists say they prefer the pointed, more forceful King to the Nobel Peace Prize-winning pacifist who preached love over hate. (AP Photo/Evan Vucci, File)
