Officers could've stopped the gunman who killed students and teachers at Robb Elementary school within minutes. That's what Texas DPS Director Steve McCraw told a state Senate committee meeting. He said there's "compelling evidence" that the response by law enforcement on May 24th in Uvalde was an "abject failure." McCraw specifically blamed the on-scene commander for stopping officers from responding more forcefully to the mass shooting. McCraw said the commander placed officers' lives before kids. He noted those inside a classroom waited more than an hour to be rescued. Nineteen students and two teachers died in the shooting.
