Keep that drama stuff out of this topic. I like discussing the laptop here because it's good to brainstorm ideas on what action I can take.
I've talked to Apple, and the summation of what I've determined is as follows:
If anyone tries to use it, or especially reinstall the OS, it will connect to the internet and email me about it being online, and where it is. To completely wipe it without going online, it takes some deep tech knowledge that I happen to have, but I doubt that these kids have.
Thank you iCloud, you're giving me hope on this.
