I remember hearing about it on slashdot, if it is true it's creepy
Slashdot Your Rights Online Story | PA School Defends Web-Cam Spying As Security Measure, Denies Misuse

Apparently the school claims it's a security measure if their laptops are stolen, and that they dont' check on students. But they caught one kid doing (what looked like) drugs and punished him for it at school (for what he did in his bedroom). So yeah, if it is true the school caught themselves in their own lie.
