The biblical witness about obeying the law/government is a "continuum" between Romans 13 where obeying is for good order and Revelation 13 where resistance against the "anti-Christ" Roman emperor would be the faithful act; Jesus is Lord NOT Caesar.  Ultimately in every time Acts 5 teaches we must "obey God rather than man".  Law is important and necessary, but not ultimate. The Good News of Jesus in John 13 has the final word: "Love one another."  Discerning when laws are just and unjust is the work of the Holy Spirit as the spirit of truth. 

What would have happened in Germany during Hitler's rise to power if Christians had resisted, broken the law, said "no"? A few resisted like Dietrich Bonhoeffer and he was martyred and is one of true heroes of the faith during that time and today.
