It's The Bill of Rights, not the bill of needs.
Thomas Jefferson: "What country can preserve its liberties if their rulers are not warned from time to time that their people reserve the spirit of resistance? Let them take arms, the remedy is to set them right as to the facts, pardon and pacify them."
George Mason: "To disarm the people [is] the best and most effectual way to enslave them." "the British Parliament was advised by an artful man [Sir William Keith] who was governor of Pennsylvania, to disarm the people; that was the most effectual way to enslave them; but they should not do it openly; but to weaken them, and let them sink gradually, by totally disusing and neglecting the militia."
Adolf Hitler: "The most foolish mistake we could possibly make would be to allow the subjected people to carry arms; history shows that all conquerors who have allowed their subjected people to carry arms have prepared their own fall."
Hubert H Humphrey: "The right of citizens to bear arms is just one more guarantee against arbitrary government, one more safeguard against the tyranny which now appears remote in America, but which historically has always proved to be possible."
In short to kill tyrants and other criminal predators.
