What about going back to WWII era Flak cannons? Not like drones running cool enough to fool heat seeking missiles can go particularly fast.

Decided to check LMSD website, and found that they posted a response to the lawsuit. It's fairly slick, and the major point they make is that when a laptop is reported missing or stolen, the 'remote tracking-security feature' (probably the webcam? They make it sound like they could activate a GPS tracker in the laptop) was used to take a still picture of the user and what the user was looking at. If the laptops were only leased to the students, and remain "school property", then I could see the implementation of such a safeguard as just preserving school property. However, if the laptops were given away to students, then it seems a bit weird that they had an anti-theft measure that they never mentioned and it's also unconceivable that they just so happened to turn on the system to find the one person who was written up for improper behavior. -- http://www.lmsd.org/sections/news/default.php?m=0&t=today&p=lmsd_anno&id=1137
