Nearly half a million people in the US are in jail right now without being convicted of a crime, simply because they can't come up with the money to pay cash bail. To try and fix this system, public defender and activist Robin Steinberg asked a straightforward question: What if we paid bail for them? In conversation with TED Radio Hour host Manoush Zomorodi, Steinberg shares how her nonprofit The Bail Project -- which uses a revolving fund to post bail for those who can't afford it -- is scaling up their efforts across the country and rolling out a new community-based model to fight mass incarceration. (This ambitious plan is part of the Audacious Project, TED's initiative to inspire and fund global change.)
