I worked in a school district and the fact is, whether in rural or urban areas, students are harmed more on their way to and from school than when they are actually in school.  In Wyoming a state law requires all school buses to have cameras to capture video of violators who drive through the flashing lights and stop sign while the bus is loading or unloading students.  That law will save more student lives than all the proposed "arm the schools" programs, and Wyoming has their share, will.
