IF . . The excrement ever hits the air moving machine, it will take not only a relitively disclipined resistance group of citizens, but also about half the military and most of the State's National Guard to push back on the Federal Government.
You can hope that the military, for the most part, does like the Military in Egypt, and maintains a relatively neutral position and as it's doing currently, pushes back against the tyranny of a developing dictatorship . .
Most of the State and local Law Enforcement agencies are "Anti-Government" and would probably fall in with the resistance . .
But you have to remember, the Government has all the intelligence advantages. They can hear you when you talk to each other, and they can see you in the dark, both on the ground and from the air . .
