In the 27 years Michael Anthony Green spent locked up in a cramped Texas prison cell for a crime he didn't commit, he often dreamed of moments like this one.
Green stood a free man on the stage of a Houston high school auditorium and looked out at row after row of teenagers.
Many were no older than Green was back in the summer of 1983, when he was wrongfully convicted of raping a woman based on faulty eyewitness testimony.
Today, as he shared his story with students he spoke slowly and solemnly.
His message was aimed squarely at salvation: stay out of trouble. Don't put yourself in the wrong place at the wrong time.
"It can happen to anybody," Green cautioned the students.
Green, 46, was released from prison on July 30 after DNA results from a pair of jeans the victim wore during the crime proved he did not take part in the rape.
He is one of 265 people in the United States who have been exonerated since 1989 as a result of the development of DNA testing of key evidence, according to the Innocence Project.
Green would never have been released if it weren't for the years he spent studying the law and petitioning the courts for his release.
"I used to go to sleep with (law) books in my hand and wake up with them," he told AFP.
