Police tactics questionned

A lot of people are now questioning whether the police effectively allowed the killer time to kill, while holding back parents on the street.

But to be fair, it is not yet entirely clear as to whether the police really could do something else to prevent the deaths (you would have to first know how quickly he killed after locking the class room door, and whether access through windows was possible) but nonetheless, it is true that the incident makes a mockery of the wingnut argument that all you need is more and more security at schools and this is readily stopped:

 

And this:

Uvalde Consolidated Independent School District had doubled its security budget in recent years, according to public documents, in part to comply with state legislation passed in the wake of a 2018 school shooting in which eight students and two teachers were killed. The district adopted an array of security measures that included its own police force, threat assessment teams at each school, a threat reporting system, social media monitoring software, fences around schools and a requirement that teachers lock their classroom doors, according to the security plan posted on the district’s website. 

It happened anyway.

I have also seen it said on twitter that shooter drills have gone on so long now in the US that a student who wants to shoot the place up knows exactly what to expect, and can work around it.
