M14 Shooter
The Light of Truth
You start as high as you can get to, and force the government to protect everyoneYou're wrong, you don't start at the top. Top people have security. You start at the bottom attacking low and mid-level governmental workers until the survivors are afraid to go to work or work from home.
More security = fewer people in the field
Credible threat = fewer people willing to continue down their current path.
If the military is using F15s and nukes against the American people, elections are an iffy proposition, at best.The less the government can provide needed services, the more dissatisfied the voters become and will throw the bums out at the next election.
