Would "school" include colleges and universities? How about barber schools? What about establishments that employ only night guards? Establishments with security guards present one weekend each year during a music festival? Do fake security cameras count?
It's easy to get carried away and see monsters under the bed that don't really exist. Rather than ban hides from every potentially uncomfortable location, I think people should use good judgment when they hide caches. I placed one on a university campus. The local police and campus security are generally well aware of geocaching and are okay with the activity. If they weren't okay with it and asked me to remove my cache, I'd gladly do so.
I think my campus cache is a clever hide. It's certainly an unusual cache that often seems to provide pleasurable experiences (57% favorite points).
