Critical Resistance seeks to build an international movement to end the Prison Industrial Complex by challenging the belief that caging and controlling people makes us safe. We believe that basic necessities such as food, shelter, and freedom are what really make our communities secure. As such, our work is part of global struggles against inequality and powerlessness. The success of the movement requires that it reflect communities most affected by the PIC. Because we seek to abolish the PIC, we cannot support any work that extends its life or scope.
