They are at it again: Oklahoma has chosen to participate in a Justice Reinvestment Initiative: its principle asset is sending people back to prison for minor infractions. The program "sends men and women on parole back to prison for the slightest infraction. Even missing an appointment or failing to pay a monthly fine." Susan Sharp, a University of Oklahoma sociology professor who has been studying the state's high rate of female incarceration since the 1990s, says, “We have set up debtors' prisons in Oklahoma.” She labels of Oklahoma's drug laws “mean” and overly punitive. She said the state's tough-on-crime sentencing guidelines are to blame for nearly all of the women serving lengthy terms in state prison.
