“The laptops do contain a security feature intended to track lost, stolen and missing laptops. ... but we were hoping to use it to catch students undressing, smoking, or masturbating. Curses, foiled again!" said a district spokesman.

So...the objective was to prevent theft of school computers, and not to peer at nude students or spy on their parents or houses, OK.

BUT:

Numerous students reported when attempting to use their OWN computers at school (computers that were NOT bugged), they were nearly expelled.

SO: the school wanted them OOOONLY to use the bugged computers, and no other computers.
