Part of a solution should be Towns setting up more political sanctuaries free from police force/ military being used to seek and detain citizens. Ithaca, NY was set up as a political sanctuary since the Cuban missile crisis. To give residents time to flee, if necessary, not using local police/ military force can be a stipulation of the city government. Of course heightened border security affects this game to flee to Canada or Mexico. Of course, this has only been used to protect citizens and ambassadors with close ties to foreign governments. What a military state will really mean, is hypothetical.
Make a local commitment to protect life within.
