用巴士运送(学生上学)

Lower courts applying the Brown decision issued desegregation orders to school districts across the country. Districts that had maintained historically all-black and all-white schools were ordered to open the doors to all comers. In some districts, desegregation meant redrawing school-boundary lines; in others, it meant busing students--usually black students--to outlying districts.
