Robert Anton Wilson was an enthusiastic supporter of jury nullification as a way to push back against the War on Drugs (see, for example, his remarks in Chaos and Beyond.)
Vox.com has published a nice primer on jury nullification, in the form of an interview with Georgetown law professor Paul Butler, who wants the rights of jurors to be better publicized. The piece is by German Lopez. Excerpt:
GL: So why should jurors use nullification to combat racial bias?
PB: If you go to criminal court in Washington, DC, today, right now, you would think that white people do not commit crimes. About 95 percent of the people who are sent for crimes in that court are African Americans, even though African Americans are only about 50 percent of the population of the District. And that's true in cities all over the country with African Americans and Latinos basically being the subjects of crime and punishment.
That doesn't mean white people don't commit crimes. It just means that they don't get the same attention, and their criminal conduct does not get the same attention as people of color.
