Justice is part of God’s integrity.
After the Tower of Babel, national governance was an institution provided by God for believer and unbeliever alike.
Old Testament theology provides volumes on the basic element of justice, courts, and a judicial system to enforce the law.
Those who seek justice independent of God, have a fundamental problem with righteousness. Those who seek righteousness independent of God have a fundamental problem with Justice (e.g. Islam).
You dwell in self-delusion if you believe the American judicial system works under the authority of divinity. A laughable delusion, in light of recent and past judgments coming out of the said system. There either is perfect justice, or isn’t. Your earlier post incorporates loopholes to exonerate the courts of their monumental failings, made possible only by thinking not unlike yours, that human-built institutions can somehow be fully trusted because of their supposed (imagined / hallucinated) ties to your flavour of divinity.
