On the first day of elementary school each year, our teacher displayed her paddle, which was wooden with a short, solid handle. The paddle portion had holes drilled through its core. Most school years, someone (always a boy, in my recollection), wound up being paddled. Times have changed for most students. But because a handful of schools in North Carolina still employ corporal punishment, questions continue to arise regarding when such punishment crosses the line between permissible school discipline and unlawful assault.
