Peace Officers Oath of Office/Code of Ethics

All states use the POST (Peace Officers standards of Training) and after graduation must take the oath of Office and sign the Code of Ethics...of which ...states may very on wording, but the gist is the same: 

Oat​​​​​h of Office

I (state your name), do solemnly swear (or affirm), that I will support the Constitution of the United States, and the Constitution and laws of the State of ..............., that I will bear true faith and allegiance to the same, and defend them against enemies, foreign and domestic, and that I will faithfully and impartially discharge, the duties of a peace officer, to the best of my ability, so help me God.  

Law Enforcement Code of Ethics 

3-2. AS A LAW ENFORCEMENT OFFICER, my fundamental duty is to serve mankind; to safeguard lives and property; to protect the innocent against deception, the weak against oppression or intimidation, and the peaceful against violence or disorder; and to respect the Constitutional rights of all men to liberty, equality and justice.

I WILL keep my private life unsullied as an example to all; maintain courageous calm in the face of danger, scorn, or ridicule; develop self-restraint; and be constantly mindful of the welfare of others.  Honest in thought and deed in both my personal and official life, I will be exemplary in obeying the laws of the land and the regulations of my department.  Whatever I see or hear of a confidential nature or that is confided to me in my official capacity will be kept ever secret unless revelation is necessary in the performance of my duty.
I WILL never act officiously or permit personal feelings, prejudices, animosities or friendships to influence my decisions.  With no compromise for crime and with relentless prosecution of criminals, I will enforce the law courteously and appropriately without fear or favor, malice or ill will, never employing unnecessary force or violence and never accepting gratuities.
I RECOGNIZE the badge of my office as a symbol of public faith, and I accept it as a public trust to be held so long as I am true to the ethics of the police service.  I will constantly strive to achieve these objectives and ideals, dedicating myself before God¹ to my chosen profession...law enforcement.
