"They tell us that we are weak - unable to cope with so formidable an adversary. But when shall we be stronger? Will it be when we are totally disarmed, and when a British guard shall be stationed in every house? Three million people, armed in the holy cause of liberty, are invincible by any force which our enemy can send against us." - Patrick Henry

"And what country can preserve its liberties, if its rulers are not warned from time to time that this people preserve the spirit of resistance? Let them take arms... .The tree of liberty must be refreshed from time to time, with the blood of patriots and tyrants" - Thomas Jefferson

The Second Amendment to the United States Constitution is the part of the United States Bill of Rights that protects the right of the people to keep and bear arms. It was adopted on December 15, 1791, along with the rest of the Bill of Rights. This store helps you express your rights.
