For decades, Oklahoma held an infamous title: the highest incarceration rate in the world. In 2016, more than 1% of the state’s adult population was behind bars, driven by harsh mandatory minimums that sentenced people to decades in prison for non-violent drug possession.

But a unique experiment in justice reform began that year, offering a powerful case study on what works—and what doesn’t—when it comes to public safety, recidivism, and the cost of justice.

The Catalyst: State Question 780

In 2016, Oklahoma voters passed State Question 780, a landmark measure that reclassified simple drug possession and low-level property crimes (under $1,000) from felonies to misdemeanors. 

• Before: A third offense for meth possession could mean 15 years to life in state prison.

• After: The same crime became punishable by a maximum of one year in county jail and a fine.

However, this change initially only applied to new cases. Thousands of inmates, like Tess Harjo, remained in prison serving 10, 15, or even 20-year sentences for crimes that were no longer considered felonies. 

The Correction: HB 1269 and the Mass Commutation

In 2019, the legislature passed HB 1269 to make SQ 780 retroactive. This triggered an expedited review process, resulting in the largest single-day mass commutation in U.S. history on November 4, 2019.

• 462 inmates were released immediately. 

• Tess Harjo, serving 15 years for meth possession, was among them. Her sentence was commuted to time served because she had already spent two years in prison—exceeding the new one-year maximum penalty.

• The state saved an estimated $11.9 million in incarceration costs for that single day’s releases. 

The Results: Did It Work?

Critics warned that releasing hundreds of inmates would lead to a crime wave. The data tells a different story.

1. Recidivism Plummeted

The most compelling evidence comes from the inmates themselves. A study of the 442 people released in the 2019 commutation found:

• Only 5% returned to prison within two years. 

• This is drastically lower than the national average recidivism rate of roughly 32%. 

• Most rearrests were for minor municipal violations, technical probation issues (like unpaid fines), or simple possession—the very addiction issue prison failed to treat. 

2. Crime Rates Remained Stable or Fell

Contrary to fears, crime did not spike.

• Property Crime: Rates of theft and larceny continued to fall after the felony threshold was raised.

• Violent Crime: Rates remained stable or declined. Preliminary FBI data for 2025 shows a sharp 9.3% drop in violent crime nationally, with Oklahoma mirroring this trend as homicides in major cities like Oklahoma City dropped significantly.

The Paradox: Tough on Violence, Soft on Drugs

While Oklahoma successfully reduced penalties for low-level offenses, it simultaneously doubled down on harsh sentencing for violent crimes.

• The 85% Rule: The state expanded the list of crimes requiring inmates to serve 85% of their sentence before parole eligibility. This now includes most violent offenses, sex crimes, and serious drug trafficking.

• No Retroactivity: Unlike the drug reforms, these harsher sentences (including recent updates in the Sentencing Modernization Act of 2025) apply only to new crimes.

The Unintended Consequence

This “two-track” system has created a new challenge:

• Rising Population: Despite the success of SQ 780, Oklahoma’s prison population has risen for three consecutive years (2023–2025), nearing 23,500 inmates. 

• The Cause: Admissions are flat, but releases have slowed. Inmates convicted of violent crimes are staying in prison much longer, clogging the system and driving up costs, particularly for an aging prison population. 

• Diminishing Returns: Data suggests these longer sentences have not produced a additional drop in violent crime beyond the stability already achieved, leading to debates about the cost-effectiveness of keeping low-risk, elderly inmates incarcerated for decades. 

The Verdict

Oklahoma’s journey offers a clear lesson for the rest of the nation:

1. Leniency for non-violent crime works. Reducing sentences for drug and property offenses lowered recidivism, saved money, and did not compromise public safety. 

2. Harsher penalties for violent crime have high costs and unclear benefits. While necessary for public safety, expanding mandatory minimums and the 85% rule has bloated the prison population without a proven corresponding drop in crime rates.

As of 2026, the state remains a battleground for these competing philosophies. But for the 462 people who walked free in 2019—like Tess Harjo—the experiment proved that justice doesn’t always mean more time behind bars. Sometimes, it means recognizing when the punishment no longer fits the crime.
