What is the nature of security guards patrolling shops at night?

It's illegal for security guards in shopping malls to patrol stores and rummage through things at night. Judging from the relevant public information, this kind of behavior is suspected of infringing on the property rights and privacy rights of shops, and also violates the professional ethics and duties of security personnel. The main duty of night security patrol in shopping malls is to protect the safety of shopping malls and prevent theft, robbery and other illegal and criminal acts, instead of entering the store without authorization and checking the goods in the store. Shopping mall security guards will be punished by law and occupation if they are found rummaging through the shops at night.
