There can be many bars, wires that keep a person trapped. All of them don't have to have been created for the purpose of harming or caging the bird, but they still serve that function.

Our prison population quintupled in a thirty year period of time. Not doubled or tripled - quintupled. We went from a prison and jail population of about 300,000 to now more than 2 million.

One study conducted in Washington, D.C. indicated that 3 out of 4 black men, and nearly all those living in the poorest neighborhoods could expect to find themselves behind bars at some point in their life.

... as recently as the mid-1970s, the most well-respected criminologists were predicting that the prison system would soon fade away. Prison did not deter crime significantly, many experts concluded. Those who had meaningful economic and social opportunities were unlikely to commit crimes regardless of the penalty, while those who went to prison were far more likely to commit crimes again in the future.

I think it's critically important for people to understand that this system of mass incarceration governs not just those who find themselves in prison on any given day, but also all those who are in jail, on probation or parole, as well as all those who are just months away from being locked up again because they are unable to find work or housing due to their criminal record.

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.
