The Bill of Rights, according to the above view, is designed to inform ordinary citizens of their rights. Its meaning is not a monopoly of the governmental entities whose powers the Bill of Rights was intended to limit. By knowing when their rights are violated, the citizens may signify their displeasure through mechanisms, such as the ballot box and the jury box, and may resort to speech, the press, assembly, and petition to denounce the evil. The Second Amendment "right of the people to keep and bear Arms" was intended to serve as the ultimate check, which the Founders hoped would dissuade people at the helm of state from seeking to establish tyranny.
