A threat and vulnerability assessment conducted by the Texas Department of Public Safety determined that the only portable radios operating inside the western Robb Elementary School building were those belonging to Border Patrol agents, according to the department’s chief of staff. McCrow. Police radios of the unified independent UValde school would not operate within the school, MacCro said, speaking to the Senate Senate Committee to protect all Texans on Tuesday, “nor does the [police department’s] … neither the sheriff’s office if he responds to help, nor the DPS officers if they respond for help. “ According to McCraw, Border Patrol has a station in Uvalde with a tower to amplify its own radio signals, but it was added when Border Patrol tried to repair the signals along with local law enforcement radios or Border radios. Patrols worked. McCraw said cell phones were able to operate inside the school, with which the principal was able to contact senders and children could call 911. “Cell phones work, they’re just portable radios that the first ones did not make – the irony of irony,” he said. He said the system needs to be replaced or the technical capabilities expanded internally, and every school in the state should also be evaluated. Within three minutes of the gunman entering Rob Elementary School, 11 police officers arrived at the scene, according to a Texas Tribune report, confirmed by a law enforcement source on CNN. Uvalde School District Police Chief Pete Arredondo called the Uvalde Police Department’s mission shortly after the gunman shot the officers, according to the source, asking for further assistance and saying he did not have the radio.
