A prison volunteer also gave him a copy of a document titled “Warrior Society” that included a code of ethics that required Native Americans to serve the people, be honorable, kind, and not steal or be stingy. A prison guard searched his cell one day in 2005, and confiscated the AIM notes, along with the “Warrior Society” document. Both were classified as “written contraband.” Greybuffalo was written a disciplinary case and sentenced to 180 days in solitary confinement. The disciplinary charge was upheld in part by a federal district court in 2010.

Always worth reminding people that “solitary confinement” is recognized as a form of torture under international human rights law.

Not that the US has ever been opposed to torturing suspects or inmates as a form of punishment. But it bares repeating.
