The trigger discipline here is something special...
Castle Doctrine / SYG doesn't apply here when there's no reasonable threat. Even in Missouri.
This is just plain unlawful brandishing
Stand Your Ground laws are broader, generally applying to anywhere one has a lawful right to be (car, office, etc). But even that wouldn't apply here
It's just not Castle Doctrine / self defense (or proper firearms discipline)
Now if the HOA came out brandishing a weapon, it'd be a different story (not least of which would be corporate personhood made manifest)
And no, even MAGAts in red hats wouldn't be a threat in this scenario. Crazy how law is supposed to work the same regardless of political views of those involved 😱
The filed plat showing it's a public road is in the thread, as is the National Register of Historic Places entry
Pay close attention to §563.031(2.)(2)
(TL;DR: you're entirely wrong)
More specifically, which Missouri statute prohibits members of the public from walking on a "Private Street"?
Yes, I saw it. That professor is quite wrong.
Now, next question: is it first degree trespass if you're traversing the private street to visit one of the houses on it?
(Trivia Note: MO passed a new statute a few years back enabling a court to force owners of private roadways to conduct maintenance)
It's functionally no different than a public road, just involving different crimes (trespass vs obstructing traffic)
If you have lawful business somewhere on that street, you're not trespassing
Part of why so many of us have been LOLing at MAGAt clowns insisting that the "Private Street" signs had some magical powers
It's not my fault you're late to the party and revel in your own mental laziness
