Highly disappointed in Hanners reaction here.
This moves on from the general "Don't talk to the police" advice. This is very specific. Roko was last heard from as a police officer harassing Bubbles, or investigating a case in which Bubbles feared arrest. And Hanners is a friend to Bubbles.
Now, in spite of that, Hannelore was nice and friendly to the officer - right up to the point where she asked a question, specifically, about Bubbles. The look on Hanners' face is both flat affect (which bluntly tells Roko that she won't respond to further questions) and "Goddamn it I extended perfectly friendly hospitality to this person and they abused it by seeking to trick me and exploit my relationship with a friend."
Unlike some folks, I'm perfectly happy to talk to police - usually they're investigating something I want to see solved and not actively trying to trick me or faking friendly interest when it's not there.
But if someone walks in who's specifically been after one of my friends who's been fucking COERCED into doing something that's technically against the law, whom I don't believe deserves to go to jail ... walks in acting friendly, and then 'casually' brings up the conversational subject of that friend.... Just. No.
Fucking no sale. You were only pretending to be friendly, now you are lying to me about no longer being after her, you're abusing my offer of friendship to you and you're abusing my friendship with her. You are despicable.
It may not actually be true in this case, but I would reach the same conclusion, and the same reaction, that Hannelore did. I'd be not giving that officer one single word more.
