The dogs can smell Glenn Greenwald long before they see him. As we drive up the hill to his house, a cacophony of barking greets us. The chorus is so overwhelming it makes me think of the National Security Agency (NSA) chiefs who Greenwald has tormented over the past year."They dont bite," Greenwald says as we are engulfed by the pack of strays that he and his partner,В David Miranda,В have rescued. After a beat, he adds: "… as long as you dont show any fear." Im not certain hes joking, which is awkward, given that there are 12 of them, ranging from an 80lb Bernese mountain dog to a rat-sized miniature pinscher.
