But doctors are required to report anything that they identify as an immediate physical threat (e.g., to the patient or because of the patient). I found out recently that this is entirely subjective - different doctors have different ideas about what constitutes a threat. So, in a lot of ways, no, medical secrecy may not protect you if you tell the wrong doctor.

While that is true it would be enough for a therapist to say they see someone as a threat. As hate for pedophiles is on a rather high level i understand the fear however unwarranted it might be. Luckely at least in germany there is some kind of help group named somewhat like "Kein Täter werden" if i remember correctly. I think we could use more of that in more countries.
