WASHINGTON (AP) — The FBI says it has helped to disrupt or prevent nearly 150 shootings and violent attacks this year, in part by steering potential gunmen toward mental health professionals. It’s an achievement that stands out during a year when President Barack Obama made curbing gun violence a priority, yet has had little success in getting new restrictions enacted.

There have been hundreds of these disruptions since 2011, Attorney General Eric Holder recently told an audience of police chiefs, touting the behind-the-scenes work of a small FBI unit based out of Quantico, Va. In most cases, the FBI has helped potential offenders get access to mental health care.
