Growing up in blue collar Circle Pines, Minnesota, in the 1950s, raised by parents from the “Greatest Generation,” I dreamed only of becoming a civil rights lawyer. My passion for justice was hard-wired into my DNA. Never could I have imagined that by the end of my 50s, after nineteen years as one of 678 federal district court judges in the nation, I would have sent 1,092 of my fellow citizens to federal prison for mandatory minimum sentences ranging from sixty months to life without the possibility of release. The majority of these women, men and young adults are nonviolent drug addicts. Methamphetamine is their drug of choice. Crack cocaine is a distant second. Drug kingpins? Oh yes, I’ve sentenced them, too. But I can count them on one hand. While I’m extremely proud of my father’s service in World War II, I am greatly conflicted about my role in the “war on drugs.”

You might think the Northern District of Iowa—a bucolic area home to just one city with a population above 100,000—is a sleepy place with few federal crimes. You would be wrong. Of the ninety-four district courts across the United States, we have the sixth-heaviest criminal caseload per judge. Here in the heartland, I sentence more drug offenders in a single year than the average federal district court judge in New York City, Washington, Chicago, Minneapolis and San Francisco—combined. While drug cases nationally make up 29 percent of federal judges’ criminal dockets, according to the US Sentencing Commission, they make up more than 56 percent of mine. More startling, while meth cases make up 18 percent of a judge’s drug docket nationally, they account for 78 percent of mine. Add crack cocaine and together they account for 87 percent.

Crack defendants are almost always poor African-Americans. Meth defendants are generally lower-income whites. More than 80 percent of the 4,546 meth defendants sentenced in federal courts in 2010 received a mandatory minimum sentence. These small-time addicts are apprehended not through high-tech wiretaps or sophisticated undercover stings but by common traffic stops for things like nonfunctioning taillights. Or they’re caught in a search of the logs at a local Walmart to see who is buying unusually large amounts of nonprescription cold medicine. They are the low-hanging fruit of the drug war. Other than their crippling meth addiction, they are very much like the folks I grew up with. Virtually all are charged with federal drug trafficking conspiracies—which sounds ominous but is based on something as simple as two people agreeing to purchase pseudoephedrine and cook it into meth. They don’t even have to succeed.

I recently sentenced a group of more than twenty defendants on meth trafficking conspiracy charges. All of them pled guilty. Eighteen were “pill smurfers,” as federal prosecutors put it, meaning their role amounted to regularly buying and delivering cold medicine to meth cookers in exchange for very small, low-grade quantities to feed their severe addictions. Most were unemployed or underemployed. Several were single mothers. They did not sell or directly distribute meth; there were no hoards of cash, guns or countersurveillance equipment. Yet all of them faced mandatory minimum sentences of sixty or 120 months. One meth-addicted mother faced a 240-month sentence because a prior meth conviction in county court doubled her mandatory minimum. She will likely serve all twenty years; in the federal system, there is no parole, and one serves an entire sentence minus a maximum of a 15 percent reduction rewarded for “good time.”

Several years ago, I started visiting inmates I had sentenced in prison. It is deeply inspiring to see the positive changes most have made. Some definitely needed the wake-up call of a prison cell, but very few need more than two or three years behind bars. These men and women need intensive drug treatment, and most of the inmates I visit are working hard to turn their lives around. They are shocked—and glad—to see me, and it’s important to them that people outside prison care about their progress. For far too many, I am their only visitor.

If lengthy mandatory minimum sentences for nonviolent drug addicts actually worked, one might be able to rationalize them. But there is no evidence that they do. I have seen how they leave hundreds of thousands of young children parentless and thousands of aging, infirm and dying parents childless. They destroy families and mightily fuel the cycle of poverty and addiction. In fact, I have been at this so long, I am now sentencing the grown children of people I long ago sent to prison.

For years I have debriefed jurors after their verdicts. Northwest Iowa is one of the most conservative regions in the country, and these are people who, for the most part, think judges are too soft on crime. Yet, for all the times I’ve asked jurors after a drug conviction what they think a fair sentence would be, never has one given a figure even close to the mandatory minimum. It is always far lower. Like people who dislike Congress but like their Congress member, these jurors think the criminal justice system coddles criminals in the abstract—but when confronted by a real live defendant, even a “drug trafficker,” they never find a mandatory minimum sentence to be a just sentence.

Many people across the political spectrum have spoken out against the insanity of mandatory minimums. These include our past three presidents, as well as Supreme Court Justices William Rehnquist, whom nobody could dismiss as “soft on crime,” and Anthony Kennedy, who told the American Bar Association in 2003, “I can accept neither the necessity nor the wisdom of federal mandatory minimum sentences.” In 2005, four former attorneys general, a former FBI director and dozens of former federal prosecutors, judges and Justice Department officials filed an amicus brief in the Supreme Court opposing the use of mandatory minimums in a case involving a marijuana defendant facing a fifty-five-year sentence. In 2008, The Christian Science Monitor reported that 60 percent of Americans opposed mandatory minimums for nonviolent offenders. And in a 2010 survey of federal district court judges, 62 percent said mandatory minimums were too harsh.

Federal judges have a longstanding culture of not speaking out on issues of public concern. I am breaking with this tradition not because I am eager to but because the daily grist of what I do compels me to. In 1999, Judge Robert Pratt of the Southern District of Iowa, a courageous jurist whose brilliant opinion in Gall v. United States led to one of the most important Supreme Court sentencing opinions in my professional life, wrote a guest editorial in The Des Moines Register criticizing federal sentencing guidelines and mandatory minimums. He ended by asking, “If we don’t speak up, who will?” I hope more of my colleagues will speak up, regardless of their position on the fairness of mandatory minimum sentences for nonviolent drug offenders. This is an issue of grave national consequence. Might there be a problem when the United States of America incarcerates a higher percentage of its population than any nation in the world?
