The only way that can be bridged or cancelled is if someone is in court and a doctor would be called as a witness in a case to testify and a judge would make that ruling.
No, not quite. As has been said, even doctors, therapists can be compelled to report something, if it is mandated by the law. For example, in many states, if the doctor - medical doctor - suspects that someone has been a victim of sexual assault, they are required to report that to the police, including the name of the person they treated. Mandatory. They don't need to have proof of assault, they only need to suspect it.
These mandated reporter laws affect therapists as well. Sometimes, it's only if they have fore-knowledge of a criminal act; if a person goes to therapy and says they are going to rob a bank, that therapist is required by law to report the criminal intent.
And, it works backwards. If someone discusses sexual abuse, of a certain type, the therapist may be mandated to report, regardless of whether the crime can still be prosecuted.
People need to look up their state laws on mandated reporting in order to real know. And it's a bit of reading, but it's the only way to honestly find out.
