"For African American children, in particular, the odds are extremely high that they will have a parent or loved one, a relative, who has either spent time behind bars or who has acquired a criminal record and thus is part of the under-caste - the group of people who can be legally discriminated against for the rest of their lives. For many African American children, their fathers, and increasingly their mothers, are behind bars. It is very difficult for them to visit. Many people are held hundreds or even thousands of miles away from home."
