Those aren’t that rare either. There are a lot of railroad crossings like that

These are all over the state

I’d agree with most of the previously stated reasons why making this information public is a bad idea, so I won’t rehash them. But I’ll add a few points. Gun permit holders are statistically less likely to break the law then police. So if you’re concerned with safety in general, there shouldn’t be much of a concern there. Also, you’re proposing making lists of citizens for exercising a right. Which other rights should we make lists on out of our personal fears? Are people who don’t answer police questions probably guilty of something? Are they dangerous? Shouldn’t the public know that guy down the street wouldn’t answer questions without a lawyer, he’s probably guilty of something, we should blacklist him. And I’d also still say you have no valid reason to know this information. It doesn’t tell you if the person has a weapon. If you honestly think they’re dangerous your simple answer is you don’t let your kid play there. There will be knives, hammers, scissors, baseball bats, any number of other weapons. Why would you ever let your kid go alone to a deranged persons home? It’s ok, they just have knives and bats so I’ll let my kid hang out over there? No, you wouldn’t. There’s no reason for that information to be public, but many reasons for it to remain confidential. If you think they’re dangerous, report them, and continue to report them each time they do something indicative of a threat, then let the professionals do their work, they have the information, and in this state they have the red flag laws to do what they need to.
