That is completely untrue, and I did not say anything even similar to that. The halachos of mesira and arakaos are live and well. All I said that was that there are times when halacha specifically mandates use of the secular system, and if you actually learned Shulchan Aruch, instead of just repeating what the street says, you would actually know this. The halachos include the מצער את הציבור that has been applied across the board to serial molesters. There are other instances when this halacha is relevant. There are undoubtedly cases, particularly of various white collar crimes, when this would be debated among poskim. Regardless, there is nothing anywhere that states that secular courts need to use halacha in their mission to convict criminals. There is also nothing anywhere that states that credible facts should be denied because one wishes them to be false.
So I am not arguing against the SA. YOu have just created your own version of halacha, and I dismiss that as nonsensical.
