"The American Black Cross’ mission is to help people incarcerated for opposing the U.S. government. The organization accepts both credit card and bitcoin donations that are directed towards legal aid, and defense funding towards criminal cases where civil rights have been infringed. Political prisoners or family members can submit a request for assistance from the Black Cross."
