The statement ignorance of the law is no excuse is centuries old:

"...Ignorance of the law excuses no man; not that all men know the law; but because 'tis an excuse every man will plead, and no man can tell how to confute him.
—John Selden (1584-1654)...

If a defendant were allowed to escape legal responsibility for his acts, merely by saying "I didn't know it was wrong/illegal", the system of using law to regulate human conduct would collapse. So the doctrine is a practical necessity...This doctrine still has vitality and validity today..."

The same source continues:

"...A related concept in law is "wilful blindness": the criminal defendant who should have known, and could have asked, but deliberately chose not to ask. The law regards "wilful blindness" as equivalent to knowledge. U.S. v. Jewell, 532 F.2d 697, 700-701 (9th Cir. 1976), cert. denied, 426 U.S. 951 (1976). Cited with approval in U.S. v. Lara-Velasquez, 919 F.2d. 946, 950-951 (5th Cir. 1990)..."
