HELP US END MASS INCARCERATION The Prison Policy Initiative uses research, advocacy, and organizing to dismantle mass incarceration. We’ve been in this movement for 24 years, thanks to individual donors like you.

Can you help us sustain this work?

Thank you,
Peter Wagner, Executive Director Donate
