Sandy Hook Promise says at the end of their last Say Something Week, a high school student in Illinois found herself confronted with the very situation she had spent all week learning about: She opened her phone and saw a former classmate holding a gun in a Snapchat photo. Because of the trainings provided through Sandy Hook Promise, organization officials say she felt empowered to Say Something to a trusted adult, and a potential tragedy was averted.  During the week of March 2nd through 6th, this program will teach thousands more middle and high school kids that they have the power to prevent tragedies and save lives by learning the warning signs of gun violence and self-harm and by saying something to a trusted adult.
