Ignorance of the law is not a valid excuse in any legal jurisdiction I know of.

I will put up a grand right this minute that there are many laws on the books you haven't a clue that exist.

Of course there are.

It doesn't mean I'm allowed to break them, however.

If people were allowed to plead ignorance, then every criminal would and it would be the state's burden to prove beyond a reasonable doubt that they really were aware of the law.
