isn't necessarily spyware (Score 1)

I haven't seen any comments to suggest: Maybe one of these kids said hey, watch this, and manually entered some tgp site into the URL bar, or googled "fuck" or something, even better used images.google.com. It could take just a few seconds to bring up a porn site with a raft of popups. I think that's the most likely scenario. No matter what, the school district is surely scapegoating Ms. Amero so they don't get sued, maybe the prosecutor or chief of police is corrupt enough to go along. A foolish and sorry business.
