There is no comprehensive national data about how many people are behind bars for a crime committed by their abuser due to laws that allow someone to be charged for the actions of another person. Accomplice liability crimes are not usually tracked by the courts as a distinct offense, and domestic violence is often not documented, so it would be impossible to account for every case.
Still, searching through legal documents, The Marshall Project and Mother Jones identified nearly 100 people across the country, nearly all of them women, who were convicted of assisting, supporting or failing to stop a crime by their alleged abuser. Some of the women showed clear signs of abuse at the time they were arrested. One had been shot by her abuser weeks before; another was in a neck brace.
This brutal, cruel system that we have is so gd awful.
