She mentioned she works on the Tor project and asks the question if her participation is relevant in this case. That part isn't made up.

I find it reasonable for someone to assume that their participation in a currently legal (but controversial) project would be a potential reason that the FBI wanted to question you.

It's not that much of a stretch to imagine that the reason the FBI are threatening to abduct her off the street and deny her the right to legal counsel is somehow related to her being a major Tor contributor.

ok thanks
