Shooter incident at elementary school in Uvalde, Texas - 19 children and 2 adults dead

The other messed up part of this is that these idiots have made life so much harder for other first responders all around the country.

Prior to Uvalde, my response would have been to totally trust that the on-scene responders were trained up to do the right thing. I would have been able to fight off my impulse to rush the school myself for fear of making their job harder. Now? I'm rushing my grandsons' school myself if there is even the hint of hesitation by the responders.
This response did more harm than Columbine. We "learned" from Columbine and changed our strategy, not waiting for SWAT during an active shooter event. Ulvade, well it's like some places didn't get the memo.
