I think it's great - more power to the people.
I can't verify this, so I hope someone can, but I was told that back in the day, jury instructions USED to contain information telling the jury they also had a right to change the law or deem the law unfit if they agreed.
So, they did not have to follow the letter of the law if they agreed 100% that the law was not valid or fitting at the time.
Since the ultimate burden for the decision lies with the jury, they darn well should have all their questions answered.
