Yeah, my limited understanding is they had some level of training on what to do in the event of a school shooting. Can't comment on the level of skill of the officers involved. I've heard of PD's having a tough time recruiting/retaining officers in the wake of "Defund the Police," ACAB, etc. Maybe Uvaldle has lost experienced folks, but I expected that to be more of an issue in the blue states and not Texas. Who knows.
All that aside, if it's possible for good to come out of an abhorrent event like this, maybe it'll crystallize the fact that "calling the cops" is not some panacea. Folks like the NRA like to tout clichés like "When seconds count, police are minutes away," but the fact of the matter is it's true. The 2018 Parkland Shooting resulted in the Coward from Broward. Maybe these guys will be dubbed the Uvalde Useless.
I supposed it all depends on the environment in which you were raised, but most everyone I know defaults to "I'll call the cops!" when serious trouble arises. As if Johnny Law will instantaneously teleport to your location, defuse the situation, and put any preparator in cuffs and a striped shirt.
Here in Chicago, violence has always ebbed and flowed. Over the years, the local government and PD seemed to be "business as usual" as long as the crime stayed in the right places and amongst the right people (i.e. on the South and West sides, and amongst the gangs and the poor). Every now and again, crime would spike in the Loop or the North side (where all the money is), and city government and PD would respond with a quickness, upping patrols and reassigning manpower until the crime abated.
Now, you've got events like this. In Lincoln Park, one of the nicest neighborhoods in the city, some dude lies in wait behind a building, then jumps out to rob someone of their phone. Guy fights back, there is a struggle, and the poor SOB gets shot twice. While the victim is lying on the ground in agony, the perpetrator demands his phone password, and once he has it, he puts a bullet in the guys head. It's like something out of a movie.
Since it's in a nice neighborhood full of monied people, the whole thing is caught in high definition audio and video via some homeowner's security camera.
In days past, this would have ignited a flurry of police press conferences and the like. Now, it's just another Friday.
Shits getting bad. It's gonna get worse. If you run into trouble, by all means, dial 911. But realize that may just get you some guys to arrive after-the-fact and take down the official report of what transpired. You may be all on your own.
As awful as it is to think about "the next school shooting," I assume it's bound to happen. I'd like to think any concerned parents will wait a hot second to determine what the cops are doing. If the parents don't see immediate action, they'll take the opportunity to jump in themselves.
