Stevens is an enemy of the Constitution, and of the fundamental rights of the American people, particularly the natural right to keep and bear arms.
So much for :
I, John Paul Stevens do solemnly swear that I will support and defend the Constitution of the United States against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same; that I take this obligation freely, without any mental reservation or purpose of evasion; and that I will well and faithfully discharge the duties of the office on which I am about to enter. So help me God.
So what did you really get wrong? Creating a legal constitutional limitations across the board. Rot in hell John Paul Stevens. You swore before God. Eternity is a very long time.
