A new executive order aims to end cashless bail in Washington, D.C. and other jurisdictions. The truth is that eliminating bail for nonviolent crimes has been a major success for safety & justice. Here are the facts:

Eyewitness misidentification is a leading factor in creating wrongful convictions, but the growing trend in police departments using facial recognition technology to identify suspects has the potential to exacerbate that problem tenfold. Will Collins, appellate public defender for DC, explains why:
Tech Won’t Fix Eyewitness Identification - Will Collins - Inquest
Eyewitness identification is a deeply flawed practice. Adding facial recognition technology, with its veneer of objectivity, only worsens the crisis of mass incarceration.

Before becoming police officers, Seattle requires new recruits to take a 720-hour "Before the Badge" training focused on becoming "community-embedded first responders". The program provides a new, holistic alternative on how we view law enforcement — not as guardians, not as warriors, but as people.

Today is #WrongfulConvictionDay

Since 1989, over 3,730 people have been exonerated in the US. Collectively, these individuals spent 34,694 years in prison for crimes they didn't commit.

A study by our affiliated faculty members Charles Loeffler and Greg Ridgeway, along with Jordan Hyatt at Drexel, estimated that 6% of state prisoners in the U.S. are innocent, which would be 75,000 people in state prisons across the U.S.

Measuring Self-Reported Wrongful Convictions Among Prisoners - Journal of Quantitative Criminology
Objectives Estimate the frequency of self-reported factual innocence in non-capital cases within a state population of prisoners. Methods We conducted a survey of a population sample of state prisoners who were asked to anonymously report their involvement in the crimes for which they were most recently convicted. To assess the validity of verifiable responses, prisoner self-report data were compared to aggregate conviction and demographic information derived from administrative records. To assess the validity of unverifiable responses, we developed a non-parametric test to estimate the probability of false innocence claims. Results We estimate that wrongful convictions occur in 6% of criminal convictions leading to imprisonment in an intake population of state prisoners. This estimate masks a considerable degree of conviction-specific variability ranging from a low of 2% in DUI convictions to a high of 40% in rape convictions. Implausible or false innocence claims are estimated to occur in 2% of cases. Conclusions The present investigation demonstrates that survey methods can provide bounded estimates of factual innocence claims within a discrete and known population. The resulting estimates, the first to formally separate claims of legal and factual innocence and to incorporate a formal measure of response plausibility, suggest that prisoners themselves are very often willing to self-report the correctness of their convictions. At the same time, a considerable minority indicate that procedural weaknesses with the administration of justice occurred in their cases. And, a distinct minority, with considerable offense variation, maintain that they are completely innocent of the charges against them.

Quattrone Center Exoneree Fellow CJ Rice asks the right question for #WrongfulConvictionDay — if we have tens of thousands of innocent people in prison in the U.S., how can we fail to reopen those cases, to seek justice for the wrongfully imprisoned, for crime victims and entire communities?

40 years ago, Charles McCrory was convicted of murdering his wife based on now-debunked bite-mark evidence. The same expert who testified at trial now says the marks don't match (and may not be bite marks at all). But McCrory remains in prison:
Bite marks sent Alabama man to prison for life. Now the expert says he was wrong
Alabama said Charles McCrory could leave prison if he just admitted he killed his wife four decades ago. He refuses.

Substances like vitamins, food, bird droppings, and even the ashes of a deceased child produced led to wrongful drug arrests. Legislators nationwide are considering reforms to address these injustices, including a Colorado task force already underway.
