Greyhound buses from Washington, D.C., headed toward New Orleans. In several states the travelers were subject to violence. In Anniston, Alabama the Ku Klux Klan attacked the buses, setting one bus on fire. After U.S. attorney general Robert F. Kennedy resisted taking action and urged restraint by the riders, Kennedy relented. He urged the Interstate Commerce Commission to issue an order directing that buses, trains, and their intermediate facilities, such as stations, restrooms and water fountains be desegregated. Effects Education Segregation in education has major social repercussions. The prejudice that many young African-Americans experience causes them undue stress which has been proven to undermine cognitive development. Eric Hanushek and his co-authors have considered racial concentrations in schools, and they find large and important effects. Black students appear to be systematically and physically hurt by larger concentrations of black students in their school. These effects extend neither to white nor to Hispanic students in the school, implying that they are related to peer interactions and not to school quality. Moreover, it appears that the effect of black concentrations in schools is largest for high-achieving black students. Even African Americans from poor inner-cities who attend universities can underperform academically due to worry about family and friends still in the poverty-stricken inner cities. Education is also used as a means to perpetuate hypersegregation. Real estate agents often implicitly use school racial composition as a way of enticing white buyers into the segregated ring surrounding the inner city. The percentage of black children who now go to integrated public schools is at its lowest level since 1968. The words of "American apartheid" have been used in reference to the disparity between white and black schools in America. Those who compare this inequality to apartheid frequently point to unequal funding for predominantly black schools. In Chicago, by the academic year 2002–2003, 87 percent of public-school enrollment was black or Hispanic; less than 10 percent of children in the schools were white. In Washington, D.C., 94 percent of children were black or Hispanic; less than 5 percent were white. Jonathan Kozol expanded on this topic in his book The Shame of the Nation: The Restoration of Apartheid Schooling in America. The "New American apartheid" refers to the allegation that US drug and criminal policies in practice target blacks on the basis of race.
