The more details that emerge about how police responded to the massacre in an elementary school in Uvalde, Texas, on Tuesday, the clearer it is that the already well-funded, heavily armed and amply trained law enforcement officers on the scene failed to save the lives of 19 children and two of their teachers. Salvador Ramos murdered 21 people. Despite earlier, misleading claims from law enforcement officials, it appears that no police officers engaged with the shooter before he entered the school. Instead of rushing in to protect the children and staff when reports of a gunman approaching the school were made at 11:30 a.m., police instead waited outside and aggressively confronted parents who were begging them to enter. The parents were threatened with arrest " one cop brandished a Taser " as they attempted to access the school to save their kids themselves. The police failed at protecting the schoolchildren, yes, but we should not be under the illusion that this is an example of the cops failing at their jobs. As far we can tell from reports, police at the scene acted as they usually do, in accordance with standard policing practice: Rather than risk a hail of gunfire to stop the killer, they kept themselves safe. It is disgusting, not shocking, that police officers would sooner harass and handcuff parents " parents begging them to save their children from a massacre " than they would run in and put themselves in the line of fire.
