@SanguineI understand why she broke a journalism rule and contacted FBI about her source.
Psychologists/Licensed Professional Counselors/Psychological Examiners, also must go by the rule of not releasing information about a patient - EXCEPT in two cases:
1. If subpoenaed to court, one must divulge the information they have.
2. If there is a present danger the patient will harm others, the mental health worker must notify law enforcement.
This journatlist must have thought the information she had presented a danger, so she contacted the FBI.
