Preach it,sister!
Speaking of movies, the one about Rubin "Hurricane" Carter is the one that comes immediately to mind. As the Wikipedia article says, either they let a twice-convicted triple murderer free, or they incarcerated an innocent man for 20 years.
But was he really innocent of any crime, prior to his conviction for murder? Let's look together:
"Carter grew up in Paterson, New Jersey, a middle son among seven children. His parents had a stable, long-lasting marriage, provided well for the family, and raised their other six children without significant problems. Only Rubin seems to have acquired a criminal record, one that resulted in his being sentenced to a juvenile reformatory for assault and robbery shortly after his 14th birthday. Carter escaped from reformatory in 1954 and joined the Army at age 17. A few months after completing infantry basic training at Fort Jackson, South Carolina, he was sent to West Germany where he developed an interest in boxing. However, Carter was a poor soldier, and was court-martialed four times for charges ranging from insubordination to being AWOL. In May 1956, he was discharged as "Undesireable," well short of his scheduled date of separation. He had served 21 months of his three-year term of enlistment.
After his return to New Jersey, Carter was picked up by authorities and sentenced to an additional ten months for escaping from the reformatory. Shortly after being released, Carter was arrested for a series of street muggings, which included assault and robbery of a middle-aged black woman. He pleaded guilty to the charges and was imprisoned in Trenton State Prison, a maximum-security prison, where he would remain for the next four years."
