Nearly 400 law enforcement officials rushed to mass shooting that left 21 people dead at a Uvalde elementary school but “systemic failures” created a chaotic scene that lasted more than an hour before the gunman was finally confronted and killed, according to a report from investigators released Sunday…

According to the Texas Tribune, which reviewed the report ahead of its scheduled release to the public later in the day, the overwhelming majority of responders at the school were federal and state law enforcement. That included nearly 150 U.S. Border Patrol agents and 91 state police officials, according to the Tribune.

“It’s a joke. They’re a joke. They’ve got no business wearing a badge. None of them do,” Vincent Salazar, grandfather of 11-year-old Layla Salazer, said Sunday.

The report followed weeks of closed-door interviews with more than 40 people, including witnesses and law enforcement who were on the scene of the shooting.
