If this our any other American Government goes rogue and begins stealing our Constitutional Rights and attacking US citizens many will not be waiting for anyone to show up at their door step. Once the Government has declared war on the people the fight is on. Many military units will turn on the Government and units that attack their own citizens. Civilians will link up with those units and police units that stand against the tyranny.
To translate, American civil war two would begin.
I believe you are wrong. It is nice to think that, but it won’t happen IMO.
The police and military will obey whatever orders they are given. They have Communications equipment that is far superior to anything we have, and that is a great advantage when calling for help.
