Guilty until proven 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, according to a Yahoo Finance analysis. 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."
