yea, school's powers over students really do overreach what I would consider legitimate. things like drug-testing for ANY extracurricular activities (some schools try all students) on the basis of the danger to students (the debate club...) is kind of insane. and yes, as a former student during the cell phone era, I found it very annoying to not be able to bring phones to campus.* I did anyway, but I was pretty bold in high school (sued my principal and school board w/ the ACLU in order to expand our rights some). it's the same as being able to read any content on a student's person, which i think is ridiculous. but alas, this will probably be held up in court

*I found it very amusing when people were praising the use of cell phones during school hours on 9/11 for students being able to contact potentially dead parents and that generally having a phone on the person is a greaty tool in society. However, demanding, with serious reprecussions, for silent mode (not even vibrate), no use, etc. during class is important. i mean, i can see this shit being used to pull of drug deals and such, but hey, that stuff is going to happen one way or another.
