What does this system seem designed to do? As I see it, it seems designed to send people right back to prison, which is what happens about 70% of the time.

All people make mistakes. All of us are sinners. All of us are criminals. All of us violate the law at some point in our lives. In fact, if the worst thing you have ever done is speed ten miles over the speed limit on the freeway, you have put yourself and others at more risk of harm than someone smoking marijuana in the privacy of his or her living room. Yet there are people in the United States serving life sentences for first-time drug offenses, something virtually unheard of anywhere else in the world.

The war on drugs has been the engine of mass incarceration. Drug convictions alone constituted about two-thirds of the increase in the federal prison population and more than half of the increase in the state prison population between 1985 and 2000, the period of our prison system's most dramatic expansion.

Now that's hard for many people to believe, given that the media image of a drug dealer is a black kid standing on the street corner with his pants sagging down.

More than 2 million people found themselves behind bars at the turn of the twenty-first century, and millions more were relegated to the margins of mainstream society, banished to a political and social space not unlike Jim Crow, where discrimination in employment, housing, and access to education was perfectly legal, and where they could be denied the right to vote.

I say we haven't ended racial caste in America; we have merely redesigned it.

The vastly different sentences afforded drunk drivers and drug offenders tells us who is viewed as disposable - someone to be purged from the body politic - and who is not. Drunk drivers are predominately white and male.
