I guess what I'm saying is, it makes it sound like they have a guy on staff (not contracted) whose whole job is to be the TOR expert. I just wasn't expecting TOR would be that important.
It doesn't say his whole job is to be TOR expert. He could have knowledge in TOR - one doesn't have to be exceptionally knowledgeable to be considered "expert" in legalese, regular working knowledge of the matter allowing him to make informed conclusions like "this set of packets is a TOR traffic going to this IP" should be enough - and other matters too.
