@Dathbgboy , nobody denied things CAN happen. I mean hell, one of the things you named was the biggest freak show in recent US history. So of course things CAN happen. But things PROBABLY won't happen for 90+% of the days your child attends school.
So to ensure that your child gets the best possible access to the content, it makes sense that Cell phones are NOT allowed in the class room.
That is all I am saying.
