If you only knew what goes around in our "justice" system between police, Prosecutors, Judges, etc. Americans wouldn't throw around the words, "We have the best Judicial System in the World" as fact. Granted, I don't have first hand knowledge of other countries Judicial systems, but unless they just flip a coin, we don't have the best system in the World.
The more appropriate saying is "We have the best Judicial System ON PAPER".
