Karen Greenberg, a terrorism expert and author of a book about Guantanamo, said it’s unknown what type of surveillance the defense is alleging, but there is past precedent. “We know that in the past … an FBI mole was put on the defense team. We know that there were CIA listening devices placed in the courtroom that even the judge didn’t know about. … We know listening devices were found in rooms where defense attorneys and clients met.”
In 2013, microphones had been discovered in the defense meeting rooms at Guantanamo, and the government confirmed that it had read some defense emails.
“We can’t even imagine what is out there now,” said Greenberg, who heads the Center on National Security at Fordham Law School.
