You may have noticed while reading the article that we have not added the image of the shooters. Most of the mass shootings prompt media to plaster all details about the shooter, which indirectly gives them what they always wanted- attention. We choose to look at the victims, hoping that their martyrdom will bring about a more just world, where massacres like these will no longer exist.
