Over the last few weeks, the Rodney Reed case has ignited a firestorm of interest, as celebrities, activists, and politicians worked to delay his Nov. 20 execution on the basis that he might be innocent. According to the National Registry of Exonerations (NRE), since 1989, 2,515 men and women have been exonerated after proving their innocence. In total, among all known exonerees, Americans have shelled out a staggering $4.12 billion to incarcerate innocent men and women since 1989. That's largely money spent on trials, and the cost of housing inmates in prison. According to the Bureau of Prisons, in the fiscal year 2017, the average cost to house a prisoner was over $36,000 a year in federal facilities. But black men make up the majority of those wrongfully convicted - approximately 49%. And since 1989, taxpayers have wasted $944 million to incarcerate black men and women that were later found to be innocent. That number climbs to $1.2 billion when including Hispanic men and women. On average, from the time a person enters the criminal justice system until they are exonerated, $1.26 million is spent per inmate who is facing the death penalty. The total sum - $4.12 billion spent on all known exonerees - also includes $2.2 billion that taxpayers have paid the innocent in compensation since 1989 for the time they were imprisoned, according to a 2018 NRE study. But while a large sum, only 44% of exonerees have ever received compensation.
