My kids both had no issues with theft that I heard of EXCEPT when S left his wallet and new cell phone on the bleachers in the school gym.
S’s dorm room had a safe built into his closet in the dorm room the school provided. As far as we know, neither he nor his room mate ever used those safes (room mate also had his own).
We strongly recommended both kids keep valuables out of sight (e.g. in a drawer or closet or on their person) so they are less tempting targets.
The kids are now done with college and still have no safe or locking footlocker or similar and have not had any theft issues.
