"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

"A free people ought to be armed." - George Washington

"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 best we can hope for concerning the people at large is that they be properly armed." - Alexander Hamilton
