Wrongful Conviction
False Allegations and Wrongful Convictions in Sexual Assault Cases: A Research Compilation
This GPS research compilation synthesizes leading studies on false allegations and wrongful convictions in sexual assault cases, revealing wrongful conviction rates estimated at 11.6–15% for rape cases, with sexual assault constituting 26% of all exonerations nationally. The data highlights that one-third of sexual assault allegations in criminal settings are classified as unfounded, that Black defendants face 3.5 times higher likelihood of wrongful conviction for sexual assault, and that real perpetrators of 154 additional violent crimes went free while innocent people were imprisoned. The findings carry significant implications for Georgia's approximately 53,000 state prisoners, particularly given the state's post-conviction review system described by its own Chief Justice as 'broken.'

Unfounded does not necessarily mean fabricated Methodology note
'Unfounded' does not necessarily mean 'fabricated.' It includes cases where evidence is insufficient to proceed, the complainant recants, or the reported conduct does not meet the legal definition of the crime. However, the high unfounded rates acro…
