Opinion: The gun violence scourge can’t be scrubbed out with one or two changes

Gun violence is so regular an occurrence in the United States that no incident, however tragic, comes as a surprise. But events in recent days deserve special attention all the same, as they underscore a core truth about responding to gun violence: changing just one or two rules would not be enough. Early this month, a 6-year-old boy shot and wounded an elementary school teacher in Newport News, Va. This, according to authorities, was no accident: The first grader pulled out a handgun and fired a bullet through his instructor’s outstretched hand and into her chest. His family says he has an “acute disability”; The Post reports that administrators brushed off concerns about the boy after he threw furniture in class, barricaded the doors to a room and threatened to light a teacher on fire and watch her die. The day of the shooting, his backpack was searched after a tip that he may have had a weapon.
