A high school student who stabbed a fellow pupil in the neck with a pencil can't be expelled under her school district's weapons policy, a Commonwealth Court panel has ruled. In fact, Judge Patricia A. McCullough wrote in the state court's opinion, every Pennsylvania classroom would be empty if her court agreed with the Pittsburgh Public School District that a sharpened pencil is a prohibited weapon. The case revolves around what happened between the 10th grader and another student at the Barack Obama International Academy on May 9, 2016.
