This is basically what Ammon Bundy did, and most of the US hates him for it. The federal government tried many times to jail him but ultimately he was found innocent everytime. Finally they managed to get him by a friendly judge who had a husband high up in the BLM, awarding an ungodly high lawsuit when he helped an innocent mother get her baby back by summonsing his protest-militia to protest a hospital that conspired to have the baby taken by child services.
Seriously, listen to some videos of Ammon Bundy actually speak (he is pro immigration rights as well, despite the 'far-right' label). Not what you hear from the media or others or under the influence of a political agenda. Most of what he says is 99% in line with your thought process here.
I live in Wyoming. Our courts aren’t being attacked.
I’d absolutely be open to lending material support to anyone looking to lawfully organise something like this in their community, however.
