The school security guards do not have the authority to manage your "radio," that is the responsibility of the law enforcement radio department, however,They have the authority to act under the guise of "campus safety" and "maintaining order."To manage your "rack" activity in a legal and compliant manner.
Different schools have different management systems, and it also depends on the individual circumstances of the security personnel. Since your school allows teachers to report to security personnel, and the security personnel acknowledge this record, then ask the other station how they handle reporting. In the future, simply report every activity, and perhaps the increased number of reports will make the security personnel familiar with the situation, so they won't bother checking.
If you have any further questions, please directly consult with your assigned tutor or professor, or ask their professors together with your classmates. Do not take action rashly on your own.
