Quote from U.S. vs. Cruickshan,
"...The right of the people peacefully to assemble for lawful purposes existed long before the adoption of the Constitution of the United States. In fact, it is and always has been one of the attributes of a free government. It 'derives its source,' to use the language of Chief Justice Marshall, in 'Gibbons v Ogden,' 9 Wheat., 211, 'from those laws whose authority is acknowledged by civilized man throughout the world.' It is found wherever civilization exists. It was not... a right granted to the people by the Constitution... The second and tenth counts are equally defective. The right there specified is that of 'bearing arms for a lawful purpose.' This is not a right granted by the constitution. Neither is it in any manner dependent upon that instrument for its existence."
