How can anyone in their right mind say that this is a good idea? Kick out the disruptive kids. If their phone rings, its a disruption. The school has no right to go through a students phone just because it's in the students possession. The "kids aren't adults" comment: Remind me how kids aren't people? The government isn't allowed to search your shit without a warrant or probable cause, why would a school have more freedom to do so?
Removing phones from schools isn't the solution either. Please stop saying "humans evolved just fine without them." Yeah, we evolved without them, but we also evolved without vaccines, health care, school, etc. That isn't any justification not to have them. Just ask students to turn their phones off, and if the teacher catches them with it out, it is placed on the teachers desk until the end of the class. Multiple violations will result in it being confiscated for the entire day.
"If no one had anything against school rules on their phones, then they wouldn't have to implement such a policy."
Please. Just because you shouldn't have anything against school policy on your phone doesn't mean they should be able to search it. Who wants to have all their private emails and conversations read, as well as pictures and online profiles that the teacher wouldn't have access to otherwise.
As I have said before on here, you all need to read 1984. It's becoming more and more relevant...
