I need your help.For more than a decade, the Prison Policy Initiative has been at the forefront of the movement to expose how mass incarceration undermines our national welfare. With a lot of hard work and generous support from a small network of individual donors, we've won major civil rights victories in local governments, state legislatures and even the Supreme Court. But
our long-term viability depends on people like you investing in our work.
Can you stand up for smart and effective justice policy by joining our small network of donors today? You can make a one-time gift, or even become one of our sustaining monthly donors.
I thank you for your investment in our work towards a more just tomorrow.
