You're not wrong, but when you get selected for jury duty the selecting lawyer will make inquiries about your knowledge on the subject and disqualify you if you admit knowing about it.
If you bring it up to the jury, that can also have you disqualified as well as anyone else the lawyers think were influenced by the discussion.
The third option is supposed to 'naturally' occurr, as in the jury agrees that the law was broken but the situation is so 'outside the scope of the law' that the law can no longer be applied. (IIRC the judge can overrule the jury in this case, but it can be a pain)
Essentially it's up to the judge to determine whether the jury's conclusion is within the realm of the 'third option'.
