So what do we do if their are no police.

Lord Of The Flies.
Not really though.
Then the federal govt is a totalitarian state that in no way resembles anything this republic has ever been.
Then the statists and globalists have won and you shut your mouth or you will be "disappeared".
Or, a convention of states is convened.
And then?
Civil war.
All things that the DC ruling class will welcome because they will be insulated from the chaos.
At least until the snake begins to eat it's tail.
That has always happened and will always happen.
Man will always yearn to have liberty and freedom.
