whether a crime or not, depending on subtle "歧视"

The recording is public information. If I can identify the person and solve the case immediately, why not let me to see the video record? Several faculties helped to see the video record. I am a faculty too, why was I always declined to watch the record and contribute my help??! It is wierd.

The main issue is: find the the thumb drive as soon as possible because the stored information (research results, passwords, information of all kinds of accounts, naked photos, birth delivery video, etc. were saved in it!) might be wrongfully used or deleted! And it is approaching winter session. No student will be on campus.
