As Uvalde Reels from School Massacre, a Look Back at Historic 1970 Chicano Walkout at Robb Elementary
Uvalde, Texas, school district police chief Pete Arredondo has resigned from his new position on Uvalde’s City Council after facing widespread criticism over his handling of the May 24 school massacre when an 18-year-old gunman shot dead 19 fourth graders and two teachers. State authorities say Arredondo was the incident commander who ordered officers to wait in the school’s hallway for over an hour instead of confronting the gunman.
