I agree with those that say the therapist is not going to report this. For one thing, it's very hard (at least where I live) to get the police to respond to much of anything since they are focused on active crimes (and, again, around here, someone has to pretty much be causing physical harm or taking over the downtown core with violent protests). I only know of two people the police responded to with amped up patrols, but that was because they were in the same circle of influence (political figures) and there were actual threats by someone who had been convicted of a similar crime. That's just to say...it's hard to get anyone to act. So I wouldn't worry about your therapist in this case, but I would definitely talk to her about ways to protect yourself in this situation.
