Minors have no "Right to Privacy" Not from a parents point of view.
Cel phones need to be "off" during school, if allowed at all.
This goes a bit far.
Cell phones should not be allowed in the school building during class periods. Put a valet at the doors, and all phones are surrendered and tagged and shelved until the student leaves the building. If they need to make calls, they can go to the office and make a call on the school phone just like the rest of us did. It'd be a good job for the superintendent that isnt doing anything about education.
