Rittenhouse was acquitted, not validated
Juries are part of the American system of justice, not its entirety. They are bound by constraints aimed at fairness and the law: the evidence they’ve seen, the laws they’re evaluating. Jurors are not experts but, ideally, objective citizens measuring the state’s effort to meet its burden of proof. The question of justice broadly is subjective but it isn’t a jury’s duty to answer that question anyway. Arriving at justice depends on the whole system, the prosecutors, the judge, the defense.
