Security video published Tuesday by two Texas news outlets shows police officers retreating from the classroom where a gunman killed 19 students and two teachers at an elementary school in Uvalde, Texas.
The video, which was recorded in a hallway and obtained and edited by the Austin American-Statesman and KVUE-TV of Austin, shows the officers arriving at Robb Elementary School at 11:36 a.m. May 24, three minutes after the gunman was seen entering the school and walking down an empty hallway.
