The initial reaction to the mass murder of children in Uvalde, Texas was horror and bewilderment. Not again. How could this happen? Perhaps you, like me, imagined that the killer shot his way into the school and wrought havoc fast, before police could respond. We were wrong. Law enforcement knew he was on his way, armed and dangerous. The door was unlocked. A good-sized contingent of police failed to act for an hour. Finally, members of an elite Border Patrol unit engaged the murderer, taking fire, and prevailed.
