Weiner was a doctoral candidate at the time of the trial, and, after the trial's end, went on to a career in academia. He went on to work in the sociology department at Rutgers University, but he has continued his activism, working with the Anti-Defamation League and AmeriCares, among other organisations. In August 2020, he published his memoir, Conspiracy to Riot: The Life and Times of One of the Chicago 7.
