I was going to post that video. First past the post is broken. Technology has far outpaced the idea when a YouTuber can draw harmless looking maps to not only decide elections but also decide how sensitive the election is to voters changing their minds on specific issues.
Jury nullification isn’t a real thing. It’s not a law in any country, it’s a “loophole” that springs out from some simple concepts.
Both of those things are important to avoid tyranny in the judicial system.
What that means is that if, for any reason, the jury decides to find you “not guilty” even against their “jury instructions” or the law itself, you’re off the hook forever. This concept is called “jury nullification” but it’s not a law or “feature” of the justice system. In fact most of the time it’s been used for very unjust outcomes, for example juries often refused to find people who perpetrated lynchings guilty because a “jury of your peers” in many states was racist AF!
That being said I LOVE to see it used to refuse unjust laws!
