Talking to law enforcement is the job of your lawyer. If law enforcement refuses to talk to your lawyer, is it really that far-fetched to think they may want to do other things outside the bounds of the usual legal process?

They're using bully tactics. Did they have to show up on her family's doorstep? No. Did they really have people watching out for her in five cities? No. Was there any reason they couldn't communicate through her lawyer? No. Did they have to speak to her in person? No. Do they have the right to circumvent her legal counsel (or make threats to do so)? No.
They're just playing mind games, like they're trained to do. Spooks gonna spook.

I don't think she's being overly paranoid in the slightest.
One possible explanation: because "Don't Talk to the Police".
That's one of the worst things one can do and really bad advice.
>Of course, she can terminate the conversation by invoking her miranda rights at any time.
That's already too late. Everything she already inadvertently said up to that point can be used against her.
