I think the role of forensic psychologist comes into actions when the investigation has identified alleged criminal and then working with the witnesses and alleged person to identify whether they are fit for trial.
Correct, no they are not at crime scenes. There has been a push for social workers to be sent out on 911 calls for mental illness, which I think is a great initiative, but isn't really what is being discussed here
