The Tarasoff decision only applies to their patients, when they have reasonable cause to believe that their patient is about to commit murder. Trump is not their patient and as such they have no idea of his mental state, nor is there any reason to think he is about to commit murder (except perhaps of the English language during one of his speeches). Their fake diagnosis is partisan, political and immoral.
