Peter Arredondo, the chief of police for the Uvalde Consolidated Independent School District, completed an eight-hour “Active Shooter Training Mandate” course on Dec. 17, 2021, according to Texas Commission on Law Enforcement public records obtained by NBC News.

He completed the same course the previous year, on Aug. 25, 2020, according to the documents…

The training course explicitly educates participants on how to “compare/contrast an active shooter event and a hostage or barricade crisis.”

Instead of sending officers in, he spent time finding keys that would let him into the school, according to McCraw.
