It's been six years since the shooting at Sandy Hook School and two parents who formed the advocacy organization Sandy Hook Promise are speaking out about preventing people from getting to the point of committing an act of violence. The group was founded by the parents of Daniel Barden and Dylan Hockley. They says they have spent 6 years wondering what their sons might look like now, what new hobbies they might have and writing down all of their memories of the tiniest details about them. They say after today, they'll piece together their hearts and keep moving forward with their goals. Sandy Hook Promise this month released a new PSA about recognizing the warning signs of violence.
