Sandy Hook Promise just helped introduce new legislation in Congress to prevent school shootings and protect more children from gun violence.  The bill is called the STANDUP Act, and it would bring gun violence prevention programs to more school nationwide.  This includes ones like their Know the Signs programs, which has helped avert multiple shooting threats.  Sandy Hook Promise officials say school shootings are preventable, with gunmen telling someone about their plans beforehand in 80% of cases. This bill would allow more students and educators to access violence prevention programs so they know how to recognize those warning signs and intervene in time to save lives.
