Hi. My dear sister, I believe you need to read the Bible a little more carefully.
In the passage in Matthew where Jesus speaks of turning the other cheek, he is speaking to the Pharasees who twisted the Law of Moses to suit their own personal adgenda. In this case, they actually used the Mosaic Law to justify their own sinful acts of revenge. And they taught the people that this was what Moses taught.
Jesus was strongly attacking the false teachings of the Pharasees and the religious system they had put in place.
Jesus never said in this passage that justice should not be pursued. On the contray, justice is demanded. Also, as a follower of Christ, I have a duty to stand up against injustice. When injustice is being commited against innocent people it is my duty to intervene. Jesus never taught us to stand on the sidelines yelling at victims to turn the other cheek.
In addition, the Law of Moses (and Paul restates this in the New Testament) teaches that the State is empowed by God to administer justice.
Please do not confuse the concepts of speaking against scripture twisting and religion (as Jesus did) with the concepts of justice and revenge and self-defense. God bless you.
