I understand that psychologists are compelled to report incidences where a patient talks about intention to hurt a specific person, child abuse, specific plans to kill themselves.
What about past crimes?
Say a patient talks about wanting to kill people. The dr asks, "How many people have you killed so far?" The patient answers honestly: two.
Does the doctor have to report this to the police?
The patient does not say, "I killed John Doe and Jane Doe on Briarcliff Avenue, November 16 2003." He says something like, "In the past I killed two people because I wanted to. I might do it again. Undecided."
In this example, both live in the United States.
