Jury nullification exists precisely because there is often a gap between legality and justice. It’s a way for the commoners to ensure justice when the nobility (CEOs and rich politicians, nowadays) make the laws in ways that exploit the commoners. It’s not so much about law vs. feelings as much as it is about offsetting the power of the powerful.
True, but we aren’t talking about whether jury nullification should exist. It already does exist and has for a 1000 years. The question is just when to use it. Like any right or privilege, it can be used unjustly. It is up to citizens to make sure it is used for good.
