Therapist Contacts Police
A patient describes to therapist Tessa Takahashi a detailed plan to shoot his former coworker Trevor Tate. Takahashi notifies police and warns Tate directly. The duty is discharged because the therapist identified the specific threat and took affirmative steps to protect the foreseeable victim.
No Warning Issued
Therapist Timothy Tang learns that patient Travis Tate intends to poison his neighbor Thaddeus Tran but records the threat without notifying anyone. Tate later poisons Tran. The failure to warn leaves the therapist exposed because the identifiable victim received no protection from the known threat.
