Unacceptable! Either tell your school this isn't right, and you will not stand for it, or move somewhere else. I do not deny that our culture has raised a certain segment of ferrel, loutish, dangerous youth, but that is VERY different from trying to guard against the next totally random and extremely rare massacre by a lunatic.
Our family decided that public school violence in our town had gotten to the point where we opted for parochial and private schools, even if we had to economize on vacations and other little luxuries to pay for it. After that, peace settled in our house again, and the anxiety we’d been living with faded into a memory.
