RUMINT is FBI has a list of ~400k US citizens to be immediately arrested in the event of martial law.
Does such a list exist? Probably.
Can the FBI arrest everyone at once? No.
That said, the FBI is incompetent enough to try so consider this: many J6 protestors are rotting in prison and still will be in prison when the order comes down. You cannot comply your way out of tyranny. When the knock on the door comes, will you fight for your freedom or join the J6 political prisoners?
@placebo The expectation of resistance is not the same as resistance. Too many weapons are lost in unfortunate boating accidents instead of being loaded and ready next to doors and nightstands.
