Do you see the chilling warning signs in this PSA about gun violence?

Our friends at Sandy Hook Promise made a PSA about recognizing warning signs for a potential school shooting. "'The one message is I want people to know that gun violence is preventable when you know the signs,' said Nicole Hockley, founder and managing director of Sandy Hook Promise. Her son Dylan, a first-grader, was killed at Sandy Hook. 'That’s a big eye opener in itself. People don’t think about gun violence in this way. We think about imminent danger, active shooter drills or lockdowns. This is about prevention.'" Watch Video
