Wrongful Conviction

The Scale of Wrongful Conviction in Georgia

The numbers are stark. Researchers estimate that 4–6% of people incarcerated in the United States are innocent of the crimes for which they were convicted (Innocent People in Georgia Prisons). Applied to Georgia — which, despite being only the eighth-most-populous state, holds the fourth-highest state prison population in the nation with an incarceration rate of 881 per 100,000 people — that translates to an estimated 2,500 innocent people currently behind bars. The National Registry of Exonerations has documented more than 51 exonerations in Georgia since 1989, with those individuals collectively serving approximately 610 years of wrongful imprisonment, averaging more than 12 years per case (Innocent People in Georgia Prisons).

The problem is both racially and demographically concentrated in ways that reveal deeper systemic inequities. Black Georgians comprise roughly 32% of the state's population but account for 50% of known exonerees. Nationally, African Americans make up 61% of DNA exonerees, and minority groups as a whole account for approximately 70% of DNA-based exonerations (False Allegations and Wrongful Convictions in Sexual Assault Cases). Some 87% of Georgia exonerees are men, mirroring the national pattern in which 99% of DNA exonerations involve male defendants. A 2014 study published in the Proceedings of the National Academy of Sciences estimated that 4.1% of death-sentenced individuals are innocent — yet only 1.8% are ever exonerated, suggesting the official record dramatically understates the true scope of the problem (Innocent People in Georgia Prisons).

Sexual assault cases are particularly prone to wrongful conviction and particularly resistant to correction. Approximately 91% of DNA exonerations as of 2020 involved sexual assault cases (False Allegations and Wrongful Convictions in Sexual Assault Cases). A Virginia study analyzing convictions from the 1970s and 1980s estimated a wrongful conviction rate of 11.6% for rape and rape-murder cases, with an upper estimate as high as 15% (False Allegations and Wrongful Convictions in Sexual Assault Cases; Innocent People in Georgia Prisons). The human cost of these errors extends beyond the wrongfully convicted: actual perpetrators identified through later DNA testing went on to commit 154 additional violent crimes — including 83 sexual assaults and 36 murders — while innocent people sat in their place (False Allegations and Wrongful Convictions in Sexual Assault Cases).

A Broken Post-Conviction System: Habeas, Time Limits, and the Sanders Problem

Georgia's post-conviction landscape is defined by a series of procedural walls erected since the late 20th century that have effectively sealed innocent people inside their convictions. Before Georgia's 1967 Habeas Corpus Act, state habeas was so restrictive that federal habeas petitions from Georgia prisoners surged from just 10 in 1962 to 211 in 1968 as prisoners sought any avenue of relief (The Unconstitutional Suspension of Habeas Corpus in Georgia). The 1967 Act briefly opened that door — but subsequent judicial narrowing and legislative revision have progressively re-closed it. Georgia is now one of a small minority of states that imposes a four-year statute of limitations on state habeas corpus petitions, a restriction that legal scholars and advocates have argued amounts to an unconstitutional suspension of the Great Writ (The Unconstitutional Suspension of Habeas Corpus in Georgia; State Habeas Corpus Time Limits: Georgia as an Outlier Among the States).

The Sanders v. State line of cases has further entrenched these barriers. Georgia courts have interpreted res judicata and procedural default doctrines in ways that prevent successive habeas petitions even when new evidence of innocence emerges, trapping prisoners in a system where the first habeas petition — often filed pro se by someone witho

Field Drug Test Unreliability: A Hidden Driver of Wrongful Conviction in Georgia

The Scale of the Problem

One of the least visible and most pervasive drivers of wrongful conviction in the United States is a technology that costs approximately $2 per kit: the colorimetric field drug test. The Quattrone Center has called colorimetric field testing "one of the largest, if not the largest, known contributing factor to wrongful arrests and convictions in the United States." Approximately 773,000 drug-related arrests per year involve colorimetric field tests — roughly half of all 1.5 million annual drug arrests in the country. Based on observed false-positive rates, the Quattrone Center estimated that approximately 30,000 people are falsely arrested every year based on inaccurate field test results.

The error rates embedded in these arrests are staggering. While manufacturers have historically claimed error rates of approximately 4%, the Quattrone Center estimated actual false-positive rates range between 15% and 38%, depending on jurisdiction and substance. In practice, documented rates have been far worse: New York City Department of Investigation testing of 71 items that had field-tested positive for fentanyl in city jails found that only 15% actually contained fentanyl — an 85% false-positive rate. Broken down by kit type, NARK II tests manufactured by Sirchie produced a 91% false-positive rate and MobileDetect tests by DetectaChem produced a 79% false-positive rate in the same NYC DOI testing. A Suffolk County Superior Court judge characterized the NARK II kits as "arbitrary and unlawful guesswork" and their accuracy as "only marginally better than a coin-flip." The Colorado Department of Corrections' own colorimetric testing program was found by a state working group to carry a 33% false-positive rate. In Massachusetts, a class action established that 38% of incoming prison mail that tested positive for synthetic cannabinoids contained no illegal drugs, resulting in 2,000 New York State inmates being wrongly punished — including through solitary confinement, suspended visitation, and loss of earned good time — based on unverified field test results. In Las Vegas, ProPublica found that 33% of cocaine field tests between 2010 and 2013 were false positives. These are not anomalies; they are the predictable output of a technology that a 2003 study in Pharmacotherapy found "lacked both sensitivity and specificity," and that the Department of Justice determined in 1978 "should not be used for evidential purposes" — a caution the National Bureau of Standards had already issued in 1974.

The National Registry of Exonerations documents that 531 of its 3,396 known exonerations involved wrongful drug arrests for substances that were not drugs. The Georgia Innocence Project has identified invalid forensic evidence as a factor in 44% of its exoneration cases. Nationally, 93% of those wrongfully convicted in field drug test cases received jail or prison sentences.

Georgia's Specific Exposure

Georgia's exposure to this problem is acute, and its legal framework makes it uniquely dangerous among all fifty states.

A 2018 FOX 5 Atlanta I-Team investigation obtained every negative drug test report from the GBI Crime Lab in 2017 and confirmed 145 false positives from field tests statewide in a single year: 64 for methamphetamine, with the remainder distributed across cocaine and other substances. At least three people had already pleaded guilty before lab results returned showing no controlled substances. A Savannah Police Department internal audit that same year found the portable drug test was wrong in 9 of 42 cases reviewed — a 21.4% error rate. A 2024 FOX 5 Atlanta poll of the Georgia Association of Chiefs of Police found that 68% of responding agencies still use roadside drug tests, and only 26% had a policy requiring additional evidence before making an arrest based on field test results. The Quattrone Center estimates that approximately 961 Georgians are falsely arrested each year due to faulty field drug test results.

The GBI's evidence backlog compounds these risks. In 2019, the GBI total evidence backlog reached 36,194 items, with 19,112 in the chemistry/drug testing section alone — more than half. Macon DA David Cooke reported 7–8 month waits for results, with some cases waiting considerably longer. In the Dasha Fincher cotton candy case, evidence submitted to the GBI lab on January 6, 2017 did not return results until March 22 — a 2.5-month wait that she spent in jail on a $1 million bond. By 2024, the GBI lab had made progress, receiving approximately 103,000 testing requests and reporting back approximately 105,000 — the first time in several years that output exceeded input — reducing the backlog by 11%. But the structural pressure remains: defendants who cannot afford bail face a coercive choice between waiting months for lab confirmation or pleading guilty immediately to secure release.

Georgia is also the only state in the United States where presumptive field drug test results remain admissible at trial for non-marijuana drug cases. In Collins v. State (278 Ga. App. 103, 2006), the Georgia Court of Appeals held that "positive field test results are alone sufficient to sustain a conviction for selling or possessing cocaine," and the precedent was reinforced by Fortune v. State (304 Ga. App. 121, 2010) under the permissive Harper standard, which requires only that a technique has "reached a scientific stage of verifiable certainty" in the relevant field. Compounding this, Georgia is the only state where possession of any amount of a Schedule I or II controlled substance — cocaine, heroin, fentanyl, methamphetamine — is classified as a felony under O.C.G.A. § 16-13-30, meaning a false field test result can result not merely in a misdemeanor arrest but in a felony conviction with career-ending consequences. There is no mandatory training in Georgia for officers on how to use field drug tests: Deputy Cody Maples, who arrested Dasha Fincher for cotton candy, admitted before a grand jury that he had received no training on the NARK II test he used.

This combination — admissibility at trial, felony exposure, no training requirements, a 68% agency usage rate, and lab backlogs creating plea pressure — makes Georgia's field drug test regime an outlier in its danger to the innocent. Black Georgians bear a disproportionate share of that danger. Nationally, the Quattrone Center's 2024 study found that Black Americans experience erroneous drug arrests from field tests at a rate three times higher than white Americans on a per-capita basis. In Harris County, Texas — where a Conviction Integrity Unit ultimately overturned 131+ convictions based on false field test results after finding that 298 people had been convicted between 2004 and 2015 despite crime lab tests finding no controlled substances — 60% of those wrongfully convicted were African American in a city that is approximately 24% Black. The innocent in Harris County pleaded guilty an average of four days after arrest, well before any lab could return results.

The Plea Bargain Trap

The field drug test crisis is inseparable from the plea bargain system. Approximately 95% of criminal cases nationally are resolved through plea agreements, and the Quattrone Center estimated that a minimum of 100,000 people per year plead guilty to drug charges relying on field test results as the primary evidence. The system is structured to prevent the truth from emerging: 89% of prosecutors surveyed accept guilty pleas without any confirmatory laboratory testing; 67% of drug labs reported they are not asked to review samples when cases are resolved by plea; and 46% of labs do not conduct confirmatory testing after a guilty plea has been entered. Over 80% of prosecutors acknowledged it is "extremely unlikely" that seized drug evidence will ever be analyzed once a plea deal is reached. In Las Vegas, only 8 of 4,633 drug convictions went to trial in 2014 — 99.8% were resolved by plea deal.

The Colorado state working group studying this issue stated the dynamic plainly: "people regularly plead guilty to drug possession offenses absent laboratory confirmation because they cannot afford to remain in custody awaiting a laboratory test." Attorney Noah Stout, who represented Holly Bennett — a 65-year-old great-grandmother from Lafayette, Colorado hospitalized for emergency neck surgery when a police officer charged her with cocaine possession based on a field test later confirmed to be false — described the systemic failure: "Everyone, at every stage, seemed to blindly trust the results of this test." Stout also identified "a huge gap between the individuals who qualify for a public defender versus who actually can afford an attorney" — defendants who earn too much to qualify for public defense but too little to retain counsel face the greatest pressure to plead. The working group further concluded: "In the absence of laboratory confirmatory testing, the incidence of false positives is largely invisible."

False Positive Cases: What Gets Mistaken for Drugs

The breadth of substances that trigger false positives illustrates why these kits cannot bear the evidentiary weight the legal system places on them:

• Cotton candy tested positive for methamphetamine in Monroe County, Georgia in December 2016, resulting in the arrest of Dasha Fincher, who spent 94 days in jail on a $1 million bond. Her federal lawsuit was later dismissed on sovereign immunity grounds. Judge Tilman Self III wrote: "Without a doubt, Plaintiff should never have spent 94 days in jail. And while the Court certainly empathizes with her, it nonetheless must follow the requisite law."
• Bird droppings on the car of Shai Werts, Georgia Southern University quarterback, tested positive for cocaine in Saluda County, South Carolina in July 2019.
• Krispy Kreme donut glaze tested positive for methamphetamine in Orlando, Florida in December 2015, resulting in a settlement of $37,500.
• Stress ball sand tested positive for cocaine in Atlanta, Georgia in October 2015, resulting in Ju'zema Goldring spending nearly 6 months in Fulton County Jail.
• Powdered milk tested positive for cocaine in Oklahoma City in August 2019; Cody Gregg pleaded guilty and nearly received a 15-year sentence.
• A toddler's cremated ashes tested positive for MDMA/methamphetamine in Springfield, Illinois in April 2020.
• IBS medication tested positive for fentanyl in Greenwood County, South Carolina in 2024; Bryan Getchius spent 15 days in jail and 7 months on house arrest.
• Lidocaine tested positive for cocaine in Jacksonville, Florida, resulting in a bond of $178,000 and more than 3 months of pretrial detention.
• A white crumb on a car floor tested positive for cocaine in Houston in 2010, resulting in the wrongful conviction of Amy Albritton, a 43-year-old property manager from Monroe, Louisiana.
• In Hillsborough County, Florida, 15 false methamphetamine positives occurred in 7 months when officers misidentified which color meant "positive."

Jacksonville's Duval County Sheriff's Office stopped using field tests entirely in September 2024 after discovering multiple over-the-counter cold medications triggered false cocaine positives.

Colorado's Reform and the Path for Georgia

In March 2026, Colorado became the first state in the United States to legislatively address colorimetric field drug testing, when Governor Jared Polis signed House Bill 26-1020. The bill passed 65–0 in the House and 33–0 in the Senate — unanimous in both chambers — and required $0 in new appropriations, as summons procedures slightly increase court workload but reduce jail booking costs. The law prohibits arrests for Level 1 drug misdemeanor possession or municipal drug possession charges when a colorimetric field drug test is the sole basis for the charge; officers must instead issue a summons pending laboratory confirmation. Before accepting any guilty plea for Level 4 drug felony possession or lower where a colorimetric test was used, courts must advise defendants that colorimetric field drug tests are subject to false positives and that laboratory confirmation is available. Colorado's reform was built on the foundation of a working group created by the predecessor bill, HB 25-1183, which found that only 4 of Colorado's 23 judicial districts responded to a survey of prosecutors — but those four unanimously confirmed that lab tests are only conducted when cases proceed to trial.

Other states have attempted reform with mixed results. California's SB 912 — the "Requiring Objective and Accurate Drug Testing (ROAD Testing) Act" — would have prohibited colorimetric test results from being used for probable cause, arrest, charging, conviction, or sentencing, but died in committee due to the two-thirds supermajority requirement. North Carolina's HB 868 — "Due Process in LEO Field Drug Testing" — has been stalled in committee since April 2025. Nebraska passed the narrower LB 519, allowing prison inmates who receive false positives to request confirmatory retesting before disciplinary action. The American Legislative Exchange Council (ALEC) finalized a model policy in January 2026 — the Colorimetric Presumptive Field Drug Test Limitations Act — that is more expansive than Colorado's law, barring colorimetric results from being used for probable cause, arrest, charging, conviction, or sentencing.

A Georgia reform bill would need to address the state's specific legal vulnerabilities through a five-part framework: (1) mandate summons in lieu of arrest for simple possession based solely on field tests, amending O.C.G.A. § 17-4-20 et seq.; (2) require court advisements before guilty pleas in cases relying on field test evidence; (3) overturn or legislatively supersede Collins v. State to remove field test results from trial admissibility; (4) establish mandatory officer training on field test limitations; and (5) ensure GBI lab confirmatory testing is completed before conviction in any case where field test results are the primary evidence. Georgia's unique combination of felony classification for all controlled substance possession, trial admissibility, no training requirements, and a demonstrated 145+ annual false positives makes such reform not merely advisable but constitutionally necessary. As Governor Kemp stated when signing the Wrongful Conviction and Incarceration Compensation Act in 2025: "Georgia values justice even when it means admitting error." Field drug test reform is the next test of that commitment.
