The Uvalde police hung around outside the school for 30 to 40 minutes doing nothing while listening to kids get murdered.
When a group of parents discussed entering the building themselves and rushing the shooter to save their children, the cops attacked at least one of those parents with a taser.
The police, upon which the citizens of Uvalde spend 40% of their annual budget, stood milling about and abusing parents as children were murdered.
Eventually a Border Patrol tactical unit arrived, asked an administrator for a key to the classroom, used the key to open the door, and shot the psychopath.
