Note to the deleted comment: note that I'm not saying that it's definitely untrue but simply that we have no way of evaluating it without something like a reference to a specific law or policy document, public comment from a named spokesperson, etc. There are enough levels of removal that the potential for misunderstanding would be high even if this wasn't touching on several of the hottest political issues at the moment, and that lack of context also affects how a lot of people might feel about it. For example, if this is true as written is that because there was a legal restriction passed setting a burden of proof for a police officer to interact with members of the public or was it something like the local sheriff not wanting to have an incident when a provocative local gun owner is insisting on their rights to free carry anywhere? A lot of people might have different opinions on the appropriate course of action based on context like that.
1. I realize some people might find this provocative but I'm thinking about how at two of the high schools I went to I had at least one classmate who'd brought a gun to school, and the second one had a mass shooting a few years after I graduated when some warning signs were apparently ignored. It's quite the contrast with the way hispanic students were “randomly” searched, and really didn't want to be found to have anything even as dangerous as a Swiss Army knife.
I think people are confused as to the types of crime police are backing off of policing. Shooting up Walmarts, schools, or churches will absolutely evoke a robust response here.
Of course, I can't speak for municipalities outside of this particular county here in flyover country. But knowing police and firefighters the way that I do, I find it difficult to believe that any school under threat would be ignored.
If you're genuinely curious, ask LEO you're friends with in your municipality, or LEO among your own family and friends to get an idea how professional LE is in your area. But you shouldn't believe everything you see on the internet. My assertions included.
