When we learned about the 17 deaths of innocent students and staff members at Marjory Stoneman Douglas High School in Parkland, Fla., we were deeply disturbed. But sadly, massacres have become more of a norm than a rarity. In 2017, nonprofit Gun Violence Archive estimated that about one mass shooting occurs per day in the United States. This is a disturbing yet undeniable trend. Two months into 2018, there have already been eight school shootings in the United States, with numerous fatalities.
