The Riseup folks had a webcam running when one of their servers was seized for running an anonymous remailer. The FBI returned the server two weeks later, without ever notifying anyone that it had been seized or returned.
I like the way the larger woman in the background is looking up at the ceiling as if for cameras. Also that the male short-haired government agent is wearing a suit, as one would expect. And then looks ~directly into the camera at one point.
