You know, with his whole "Tyger Tyger" organization that has been shown around this season. I think that Tommy Volker was involved in this organization. He was very powerful, and he had powerful political connections. Maybe that's why Kirkland told Lisbon to stop her investigation with Volker, because Homeland Security already suspected this secret organization.
Maybe Volker could provide some info for Jane and Lisbon about RJ during this season

What do you think?
