The FBI arrested him in a hallway, 1 day after his talk. Dmitry at first thought it was a joke put on by a Defcon prankster.
During his talk, the panel moderator asked Dmitry to pause for a minute... and said "Would you mind saying 'Can you tell me where are the nuclear vessels in Alameda'?"

The mostly American Trek-familiar audience had a good laugh, and Dmitry continued with his talk.
