Any competent explanation of why our prison population has grown by 700 percent since the early ‘70s will involve a number of factors, including changes in demographics and in the way prosecutors charge defendants. But new research confirms what sentencing reform advocates have been saying for years: we have so many more prisoners because we’re locking people up for longer than ever before.

As states begin to realize that they can reduce their prison populations safely, the pace of reform has begun to pick up a bit this year. State legislative sessions are coming to a close, which makes it a good time to review the actions lawmakers have taken to reduce their unsustainable prison populations in 2012. Here are the some of the legislative reform highlights:

Alabama

Faced with a system of overcrowded prisons and fearing the same sort of court order that forced California to reform its prison system, Alabama took an indirect route toward depopulating its prisons. The state passed SB 386 inMay, which will allow the Alabama Sentencing Commission to set sentencing guidelines for nonviolent crimes that judges would generally have to follow. Under the new law, the Commission can make sentencing changes for nonviolent crimes, which will take effect unless the legislature takes action to reject any such the changes. The Sentencing Commission, which is insulated from the electoral pressure to reject proposals to soften criminal sentences, may now be poised to take action to reduce prison sentences for nonviolent offenses.

Texans can sleep more soundly at night knowing that Elisa Castillo, a grandmother and nonviolent first-time drug offender, is serving a life without parole sentence in Fort Worth. Yes, you read that right — the latest casualty of our War on Drugs is a grandmother who never even touched the drugs that sent her to prison. Though she may not look like public enemy No. 1, our persistently illogical criminal justice system has determined that this harsh punishment fits her crime. The truth, though, is that her fate was sealed, in large part because she didn't have a card to play when negotiating her sentence.

Today, the U.S. has the highest incarceration rate of any country in the world. With over 2.3 million men and women living behind bars, our imprisonment rate is the highest it’s ever been in U.S. history. And yet, our criminal justice system has failed on every count: public safety, fairness and cost-effectiveness. Across the country, the criminal justice reform conversation is heating up. Each week, we feature our some of the most exciting and relevant news in overincarceration discourse that we’ve spotted from the previous week. Check back weekly for our top picks.
