Is there an expectation of privacy on a PUBLIC resource?
You didn't read my earlier post carefully enough I think. If the resource and ONLY the resource is monitored, such as by using GPS, then there are no privacy concerns, no "collateral damage" so to speak.
Once you turn on a video camera the "collateral damage" begins and yes, there is an expectation of privacy SURROUNDING the public resource.
You can't claim innocence in the following case: You decide (legally) to blow up a tree stump using dynamite. But the only kind available to you would also blow up your neighbor's house.
You DO NOT HAVE THE RIGHT then to proceed to blow up your neighbor's house along with the stump simply because the existing technology was not capable of doing only the limited job you initially intended.
“Is there an expectation of privacy on a PUBLIC resource? “
Are you seriously asking that question in regards to someones home? If the school is stupid enough to provide laptops to students they should expect to write every single one of them off.
