Kcbs In Depth

Month after month, year after year mass shootings continue to take place in America, traumatizing communities all across the country and fueling the bitter, seemingly intractable debate over gun control. But amid the horror and the hopelessness, largely hidden from public view, teams of people within law enforcement and mental health circles have been quietly working for decades now to develop new methods to identify possible shooters and to intervene before an attack ever takes place. How far could this work really go toward stemming the tide of violence? It’s a question taken on by journalist Mark Follman in his new book, "Trigger Points: Inside the Mission to Stop Mass Shootings in America." He joins this edition of KCBS In Depth to lay out what he's found.  Host:Keith Menconi
