I agree that the jury should certainly have the power of nullification. And I believe a jury should be made fully aware that they have such power.
However, they also need to be aware of how that power has been (mis)used in the past, and understand that nullification should be seen as an extraordinary act of civil disobedience on par with a full-fledged riot in protest of the law in question.
Nullification is not something to contemplate lightly. If you’re going to be nullifying the law, you should be spending most of your deliberations writing a unanimous joint statement to the press, to be issued as soon as the jury is dismissed.
