Cat-Tribe's facts are usually section of laws or court cases too. Some of those laws are usually Federal or State laws, so that it could be more applicable. Tell me, which federal/state law or court case require a police officer to follow an ethical code of conduct?
None. I am not an advocate for "ethics laws" or whatever you would call it for police, but you don't see anything wrong with somebody who is trained to kill people and imprison them not knowing why their actions are justified? Whats the difference between a cop and a serial killer?
None. Because their situation fluctuates when they do their jobs. Their victims can become suspects. Their suspects can become victims. Their suspects can be the kindest old man in the world. Their victims can be an evil old witch (not wiccan). If they follow what you would call "ethics" or to follow an "ethical" law, they would have to do their jobs with extreme prejudice. Not to mention if they have "ethics" that it would conflict with the most basic laws.
Ethics actually aren't as "relative" as you would think. I know that its extremely difficult to prove that statement without referencing you a book to read. But the fact is that systems built on unethical practices end in failure (soviet union). Natural Law is a universal code of ethics.
That's why police officers don't have "ethics" when doing their jobs. They can have such things when they're not wearing a uniform, but when they have a badge on, they require quick-thinking. Not ethics. Also, this is why we have a judicial system. To see if the law they are enforcing is just. That's why we have judges in courtrooms. If you want police officers to use their "ethics", that means you want a judge as police officers, followed by a group of jury following them around to see if their ethics is just or not.
What makes a cop different than a serial killer then if there are no ethical considerations involved in murder and imprisonment?
