> I’m with you on some liability for the conviction of innocent people, but that liability should also extend to juries.

You have to be careful here. Doing so can create perverse incentives that undermine justice. If a judge or a jury face such penalties, they will be inclined to reduce the penalty or feel compelled to find the defendant not guilty as a fearful precaution, even in cut and dry cases. And would you punish innocent jurors where unanimity is not required?
