He purportedly has video of the bag men. When he was in the US his girlfriend woke up to another bag man watching her through night vision goggles, presumably while his partner installed bugs in the apartment while Appelbaum was out of town.
Totally agreed there: There's no level of security policy measures that would make this guy paranoid.

It's interesting that I learned what guerilla strategy is from a robot in a science fiction movie.
Scene from the movie "Red Planet" from the year 2000: http://youtu.be/GltSAI25gaA?t=5s
Story in this scene: The reason why the AMEE didn't kill the Astronauts, was because it wanted leave a wounded back, to demotivate the moral of the others, so that they choose worse strategies to fight against AMEE's plans. One of the Astronauts asked, why didn't she kill all of us and only wound him. The other guy said: It's because she knows all about "Guerilla Strategy" and she applies that to reach her goals. She punctuated him, so that he will die, but slowly, which is to break our moral.
Pretty sure the "bag man" idiom doesn't mean what you think it does.
