We just went through a cycle where an entire nation of TikTok users were shown videos of students vandalizing bathrooms. The larger object you could steal, including entire urinals and toilets, the better. Search on "devious licks" and you'll find dozens of school districts that were fighting this problem.

At my local HS the answer was to close most of the bathrooms during class time and monitor visits, since putting live cameras in the bathrooms would cause an even larger uproar. Students always had access to a bathroom during class time, just one up near the admin offices that could be more closely observed.
