I think US needs some improvements in their judicial system. Justices in SCOTUS are sometimes too political and arrogant.
1. Candidates of new SCOTUS Justice is nominated anonymously by all Judges in the judicial system. 2. Justices in SCOTUS are subject to review and rating by all judges annually. The Justices with lowest rating who fails the passing rate (I suppose that there is a passing rate) for 3 times will be replaced.
