I wouldn't - the jury's charge is to determine guilt.
Well, in this case, I would convict the guy too...
BUT, aside from this guy, I will say that the jury's job is also to prevent unjust laws from being carried out on citizens, and "Jury Nullifiction" is also within the rights of a jury to carry out.
I know that Judges and DA's and other authorities don't like this -- but this is a good conservative protection for this country and its people...
As I said, I'm not talking about this guy, but I'm talking about the duty of the jury in cases where there are unjust laws and "Jury Nullification" comes into play. That's a duty of the jury, too.
However, as you point out, it's not really an issue in this case.
