8 - 5: Nullification

After the cops trace an eagle tattoo on a man shot and killed while holding up an armored truck to a group of militia members, McCoy finds himself facing one of their number as the pro se counsel for his friends, arguing for the concept of "jury nullification", the right of a jury to protect a defendant from an unjust law by acquittal despite the evidence.
