I thought this list was common sense honestly, and some seems a bit paranoid to me. If you keep your stuff on you or in your room, and lock your room (something I assumed everyone does whenever they leave or frankly close the door), I don’t see any need for hidden containers or computer anchors excluding maybe a small safe for stuff like incredibly valuable personal items if you really need the peace of mind.
Is this actually a big problem? I haven’t heard of a single case of it at my school personally in a year.
