It is hard to forget the horror-stricken faces of Stoneman Douglas high school students. They lost their classmates and favourite teachers in a mass shooting incident that shook the world. In the past few years, the intensity and frequency of gun violence have increased tenfold. Almost every month, you hear some case of gun firing in a residential or school area without any cause. This has created an environment of terror for all the kids and parents around the world and has greatly impacted their behaviour and education.
