The U.K. judge in the #AssangeCase cited conditions at the Terre Haute, Indiana penitentiary in her ruling against a U.S. request to extradite #Assange to the United States. Also Carswell in Texas, where Lisa Montgomery is being held. https://www.judiciary.uk/judgments/usa-v-julian-assange/

"Regarding post-sentence confinement Mr. Sickler states that the most likely BOP facility placement given the charges and potential sentence length is at one of the two Communication Management Units (CMU’s) in Indiana or Illinois. ...

"He states that in CMU’s verbal communication between inmates is monitored, visitation privileges are severely limited and physical contact with visitors is completely banned."

In a separate section she acknowledges the possibility that #Assange could end up under a draconian "special administrative measure" at Terre Haute. Under some SAMs, the government is able to monitor inmate communications including attorney-client communication.

"It is an agreed fact that there are currently nine inmates subject to a SAMs for espionage, of which four are housed at the ADX Florence, one at MCC New York, two at FCI Terre Haute, one at FCI Hazelton, and one at FMC Carswell."
