If you don't know, then you don't know. You certainly can't and would not be held accountable for that. The prosecution would have to prove knowledge on your part. That is usually pretty hard, even with some "slam dunk" cases I've seen.
You sure about that? What about that "ignorance of the law is no excuse" phrase?

Other folks are advising reasonable precaution; you're advocating he loudly sing "Mary had a little lamb" and pretend he couldn't know about this potentially illegal act. That's not good advice.

It's kind of like checking your backstop. "I didn't know" just doesn't hold up all that well as an excuse.
