Sorry, dishwashing guy.
It's too bad that that line is so horribly abused. It was originally meant to refer to not knowing that there were actually laws against an immoral act undertaken. It was *not* meant to imply that everyone needs to be an omniscient lawyer.
I will put up a grand right this minute that there are many laws on the books you haven't a clue that exist.
Considering how convoluted our legal system has become, I would submit that we're all ignorant of many laws. It's the nature of government to seize freedoms, and they're doing just that by creating statutes that are impossible for any person to actually understand.

No. This is an administrative punishment, meted out by the executive with no oversight, and no access to justice.
What about the Kingdom of God?
