Mark 12:30…says nothing about the law, or hanging. You're twisting of the scriptures to fit your narrative is noted, shill.
Jesus was condemned by the Pharisees for protesting the excesses of the temple (the church) and working on the Sabbath, a violation of "The Law", and tortured/crucified by the Romans in performance of their duties to uphold "The Law", and carry out the punishments prescribed by the Jewish Sanhedrin.
