Communication Management Units, or CMUs, are cloaked in secrecy. They segregate prisoners accused of terrorism, stripped of rights and held in isolation:
We sat together on her couch, her small, eight-year-old hands clutching a photo of her father, Yassin Aref. “My daddy only held me twice before I was five,” Dilnia told me. For the first five years of her life, she only knew him as the man on the other side of a plexiglass window in a communication management unit in an Indiana federal penitentiary.
Prisoners describe the communication management units, or CMUs, as “Little Guantánamos.” In 2006, the Bureau of Prisons created two of these units to isolate and segregate specific prisoners, the majority of them convicted of crimes related to terrorism. The bureau secretly opened these units without informing the public and without allowing anyone an opportunity to comment on their creation, as required by law. By September 2009, about 70 percent of the CMU prisoners were Muslim, more than 1,000 to 1,200 percent more than the federal prison average of Muslim inmates.
