Dedicated camera? What are you talking about? Policy wise, if the teacher thought he was a security risk he would not have returned the camera and would have been required by law to report the student. The teacher doesn't have the authority to determine that the student is not a threat. Also, asking two questions is hardly grilling the kid. I do teach. Students at my school, like most schools, are not permitted to bring cameras to school. In the current political atmosphere, the student and the parent should know better than to show off pictures of a gun, even a bb gun, at a school. Taking 5 days to tell his parents shows how completely unthreatened and unaffected the kid was by this.
