The U.S. Secret Service issued a guide aimed at preventing school violence on Thursday, in response to the Valentine’s Day mass shooting at Marjory Stoneman Douglas High School in Parkland, Fla., which left 17 people dead.

“The Marjory Stoneman Douglas High School shooting tragedy served as the impetus to go beyond our past work and go in depth regarding the how — how do we solve this epidemic?” said Secret Service Director Randolph “Tex” Alles, according to a U.S. Secret Service press release. “The report truly is an operational guide and I am confident that if embraced and followed by our nation’s communities and schools, that we will together reduce the occurrence of violence and the tragic loss of life.”
