How America Stops Mass Shooters — Poorly. By JIM GERAGHTY
Excerpt: There are times when it feels like the slogan and instruction to the public, “if you see something, say something,” is a cynical joke. We heard about police and the FBI ignoring warnings about the Parkland shooter. Mass shooters at Virginia Tech, Aurora, Tucson, Isla Vista, and Sandy Hook all had one thing in common: Before the shootings, concerned and frightened people who had encountered the future shooter told various non-police authorities about what they had seen and heard — in some cases, campus police; in other cases, college and school administrators. The El Paso situation is not quite one of these. The shooter’s mother was concerned enough to call the police . . . but not concerned enough to give his name.
