The mass incarceration of poor people of color, particularly black men, has emerged as a new caste system, one specifically designed to address the social, economic, and political challenges of our time.

We're living in a time when so many of the civil rights and social justice organizations are run by lawyers and policy people who are often very disconnected from the communities they claim to represent.

I was inspired by what students have done in some schools organizing walkouts protesting the lack of funding and that sort of thing. There are opportunities for students to engage in those types of protests - taking to the streets - but there is also writing poetry, writing music, beginning to express themselves, holding forums, educating each other, the whole range.

In the 1990s - the period of the greatest escalation of the drug war - nearly 80 percent of the increase in drug arrests was for marijuana possession, a drug less harmful than alcohol or tobacco and at least, if not more, prevalent in middle class white neighborhoods and college campuses as it is in the 'hood.

Prison guard unions have become the powerful political forces in some states, particularly California.

If the drug war was waged in those communities it would spark such outrage that the war would end overnight. This literal war is waged in segregated, impoverished communities defined largely by race, and the targets are the most vulnerable, least powerful people in our society.

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.
