As much as most people on the left want juries to nullify in cases of unfair or unjust laws, the reality is it mostly results in murderous cops going free and corporations getting free passes. Like I said in another comment, while jury nullification could be used to tackle unfair laws, the reality is you mostly end up with actual racists and actively harmful corporations not being held accountable. Jury nullification is itself not good or bad, but it’s mostly used for bad. Frankly, I don’t really love the jury system but that’s a while bigger issue.
