This is somewhat unreasonable, but it's difficult to argue with its effectiveness even if unpopular and inconvenient. The high school I attended (Leland of SJUSD) in the mid 90's ripped out all of its lockers in the 70's or 80's. (The lockers were on the exterior of buildings of an open campus.) The legend is that unknown person(s) were placing incendiary explosive devices in them and blowing them up, causing a real safety hazard due to shrapnel caused by the lockers themselves. Supposedly, they couldn't allow the risk of having an explosion during school hours and associated injuries. Therefore, all students had to carry heavy textbooks. https://www.google.com/maps/search/leland+high+school/@37.2173703,-121.8448555,56m/data=!3m1!1e3 https://www.google.com/maps/search/leland+high+school/@37.21...
