Which codified law, excluding religious commands, has been memorized word-for-word by the most people? The only ones I have memorized are Constitutional amendments.
"Congress shall make no law respecting an establishment of religion, or prohibiting the free excersize thereof, or abridging the freedom of speech, or of the press, or the right of the people peaceably to assemble and to petition the government for a redress of grievances."
"A well-regulated militia being necessary to the security of a free state, the right of the people to keep and bear arms shall not be infringed."
"The trial of all crimes shall be by jury..."
"Neither slavery nor involuntary servitude shall exist within the United States, except as a punishment for crime..."
"Congress shall have the power to lay and collect taxes on incomes, from whatever source derived..." (definitely the most popular law)
And if you count Supreme Court cases, "Roe and Casey are overruled" and "The Constitution does not confer a right to abortion."
I wouldn't be surprised if the most memorized law is the First Amendment?
