Josh Tepfer’s black backpack “is to the attorney who frees the innocent what the cape was to Superman, the hammer to Thor — the tool that helps him do the seemingly impossible. And at scale. In it, he carries the briefs, files, and other paperwork that allow him to seek the release of people convicted of crimes they didn’t commit — the raw materials from which he crafts their freedom, renews their spirits, and clears their names.” The bag has been doing some pretty amazing work. Tepfer has gotten 288 wrongfully convicted people out of jail. How has one guy with one backpack had that kind of impact? He’s pioneered a strategy called mass exoneration, in which “groups of those unfairly convicted who have similar complaints — mostly based on repeated misconduct by police or other officials — are cleared at once rather than each person’s appeal having to make its way through the court system.” Melissa Segura in Buzzfeed: A Chicago Attorney Is Getting Justice for Hundreds of Wrongfully Convicted People All at Once.
