Light – hearted hyperbole. But essentially true nonetheless
Ballot box: Public, free, democratic elections. If the laws don’t work, and the elected representatives don’t get it, replace them.
Jury box: If no public representatives get it, neither the elected nor those available to elect, the second to last line of defense is the judicial system, which can overturn laws that go against the most fundamental rights.
Ammo box: If the system has been so thoroughly corrupted that the entire establishment is acting as one, and it is not possible to change the laws to safeguard fundamental liberties, then only one option remains.
